Incorrect assumption - as a result,
...your math is wrong.
60 psi is 60 psi, period. If the tire pressure in the truck is 60 psi, then the pressure on the road is 60 psi. You can't double the tire pressure and triple the pressure on the road as a result - you'd have a truck that either bounced, or sank. Newton's laws (net vertical force = 0 for no acceleration in the vertical direction) have to be met.
It doesn't matter if my math is wrong or my assumption about surface area is wrong. The simple fact remains that the tractor trailer has 14.666 times the weight of the car but only 4.5 times the number of tires of the car. Even if that means that factor of 3.25 is completely compensated by the tire in a ratio of 60/35, you're still applying roughly double the pressure over an area 3.25 times greater, 4.5 times as often.
(regarding PSI, while I think your assumption probably roughly holds, we also have to take into account the fact that as these tires have a different composition, they are also going to dissipate weight differently. Tractor trailer tires are not only larger, but they are also thicker. That means that there is more rubber in each tire to distribute force from the truck to the road. i.e. its tendency to deform as a result of weight applied is what affects its PSI. Consider an extreme example: A fictional monster truck tire almost completely rubber with a very small chamber inside the tire. If it is sufficiently small, you could even create a vacuum inside this chamber, and the structure of the tire could still handle the stress. So, regardless of the amount of fictional weight you placed on the tire, that chamber would still have a PSI of 0 because there's no actual gas to be pressurized. Thus, if the tractor trailer tire has more structural rigidity, a higher portion of its weight is directly applied to the road via the resistance of the tire to deformation from pressure.)

I usually get the battery life as advertised by Apple. Though I turn the screen down to two or three bars (usually three since it often flickers at two). The Macbook is also mostly used for light computing such as web browsing with Flash disabled via the Flashblock add-on for Firefox, viewing documents in MS Word or Adobe Reader and rarely watching a DVD ripped to the hard drive (only when flying).
I could see people easily getting less battery life by leaving the brightness up, playing games or leaving Flash enabled when web browsing.

You guys are forgetting that the LV and ULV version of the HD3000 is underclocked compared to the normal voltage version. So while the normal ones are the same as the 320M, the underclocked LV and ULV ones are definitely not going to match up to the 320M.
even the normal ones cant match up to the 320m esp in windows so i wonder how a 6EU underclocked/volted HD3000 would be able to catch up:mad:

Why would one jailbreak? What is the benefit? Just curious as I haven't updated yet. Thanks!

Garmin, a little late to the game aren't we?
As for downloading maps on-the-fly, bad decision. True, I went many years using Google Maps for directions without major problems, but there definitely were some major headaches along the way. I can remember critical times when the I would be staring at a blue dot amongst a sea of gray. I mean, I still alive, so it couldn't have caused much trouble, right?

There is absolutely zero logic to the rest of your post either. How has this helped the music industry exactly?
Like i said above, without the RATM thing, only a few thousand people would have bought Joe's single and practically no-one would have bought RATM. Having some competition, inspired people to buy the song they liked. More people bought Joe's and RATM's music than if there would be no 'rebellious campaign'. More money in a industry makes it a lot healthier. Especially for Sony.
As I have said all along, the UK chart is a glorified popularity contest. The most popular record, at the time, wins.
Correct me if I'm wrong but isn't that the general idea of the charts? :confused:
People don't just buy the xfactor winners single because of the name - they buy it because they like it (and it's usually more than a few thousand btw)
Since the demise of the chart show and top of the pops in the UK, the xfactor is really the only music show on telly. Meaning that it is all that the TV viewers see. The common working person who slumps on the couch, tired on saturday night, and watches the xfactor, isn't going to spend their time searching for other music available, when the music comes easy on the TV. With no other music on such a big TV show, it gives the xfactor a kind of a monopoly.
They may like it, but in their eyes (or ears), it's the only thing to like, because they simply don't have the time or the interest to search different genre's of music.
There has also been no significant reduction in music piracy as a result of this campaign - I guarantee it.
But I can guarantee more people have bought music. I certainly have.
There has been no 'rebellion'.
Yes there was. If there was no rebellion, RATM would not have even been suggest for xmas number 1.

I would like to know if all these people swarming to buy the RAtM track actually care about Christmas number 1's. I wonder if anyone does?
Of course they don't. Most of them probably just want to be involved in the commotion, so they can put their hand up and say "yeah, I downloaded that track, suck it Cowell!"

Sony had a lot of innovative products in 2010 but they (for no discernible reason) decided to discontinue all three products (VAIO Z, X, P).
The P fits in my pocket, the X is insanely light and thin (and somehow managing to shoehorn internal Ethernet and VGA to something that's lighter/thinner/smaller than the Air) and the Z was simply astonishing. Non-LV i7 proc, GT330M graphics, 512GB SSD, Blu-ray and a Full HD 13.1" LED screen (covering 96% of Adobe's RGB colors!) in something that was the same weight as the last-gen 13" Air.
Why they discontinued them I'll never know. Glad I bought them while I could :)
And somehow having to buy/carry around another bulky dongle, and using up another one of the USB ports, is better?
Not to mention that the internal Ethernet port could support up to Gigabit speeds while the extEthernet would only support up to 100Mbps (due to USB's limitation of 480mbps).
Yeah, all of the above limitations/annoyances sounds way better than having a collapsible Ethernet port :rolleyes:
...and GTX460M in an Air? Yeah good luck with that. Do you want worse battery life and a melted casing or what?
You do realize that the 410M is a dedicated graphics chip? There is no space for a dedicated card on the Air's mobo.
Besides- the 410M performs slightly worse than the HD3000 and is thus worse than the current 320M. And thus, if you doubt the HD3000 can run OS X at a 'retina' resolution, good luck with the 410M. The only thing going for the 410 is the better NVIDIA drivers.
See above.
We'll see. I highly doubt it, but we'll see.
Sony has proven that Apple could get more features in the same space. Unfortunately, I dont think Apple cares about features if it interferes with differentiating product lines.
What the MBA gets will depend on what it replaces (if anything).
Apple has confirmed however, that the MBA type of laptop is still highly desired. Now lets hope they put more into it while keeping the cost low. Cost was, in my opinion, what ultimately killed sony's ultra portable lines.

I feel embarrassed watching them.
Exactly. I find the Mac character to be very smug and condescending. I don't like being associated with that just because I choose to use Macs. I've talked to several people about the ads, and most find them to be offensive because of the elitist attitude. It's not just "Look at how great I am," but it's "Look at how crappy you are, too." Nobody likes being told they're crappy.
Some people I know just dismiss it as an ad for a product they'll never buy. A few told me they ultimately dismissed it before really considering the Mac argument because it seemed like all fluff and no substance (that seems to be a common perception among people who avoid Macs: that they are all about style and not substance). Other people said it actively made them want to do anything to hurt Apple - not only by not buying the products, but advising everyone they know to stay away as well.
I can't think of one person I've talked to who found the ads to be completely positive. The people I know who like Macs were all a bit uncomfortable like me, being stereotyped as smug and elitist.
The big problem with these "hello, I'm a Mac" commercials is that they're an easy target for parodies.
Yeah, they're easy to parody because they're made so simply. Same as the "switch" ads. Speaking of parodies, this one's my favorite:

I always assumed it was monkeys, so I guess interns would be a step up.
Yeah, for a $99/yr offering, it's stunningly meager.
Well that would explain a lot. :D
But seriously though, it's not that much that is missing from .mac to make it worth the $99 without regrets.
Like:
- fully editable web calendar
- fully editable address book
- spam management
- more storage (2GB would be sufficient)
- make the Finder fast so iDisk is actually usable
- web editable blog synched back to iWeb
- possibility to show subscribed iCals in web interface without having to visit their site
- integrate stickies into .mac and synch them
With those things, that would be fairly easy to do I don't think a lot of people would complain anymore.
And it's not really something completely new, just evolution of the existing.

A car that gets 60 mpg will do just as much 'damage' to a road surface as a car that get 8 mpg....but the 50mpg car will pay much, MUCH less for upkeep of that road than the other in a gas-tax based situation.
so a prius does the same amount of damage to a road as full size RV?
