It might - read below.
It's not weight that damages the roads, it's pressure. Too much weight concentrated on too small a space is what damages asphalt (and concrete, to a far lesser extent). That's a function of pressure in the tires - two vehicles with the same tire pressure are doing the same amount of damage to the road, regardless of their respective weights.
True enough, a truck weighted down with a full load might have 60 psi in the tires, whereas most passenger cars are in the 30-35 psi range. But in this sense, a small car and a big car (or light truck) are doing about the same amount of damage to the road.
Here in north Texas, it's very true that the majority of damage to the roads comes not from any vehicle, but from unstable soil underneath the roads. I imagine there are many places across the country where this is true.
An 18 wheeler tractor trailer has an empty weight of 36,000 lbs, or 18 tons. Law permits up to 40 tons loaded. Let's assume a light load and say 22 tons.
That's 1.2 tons per wheel.
A prius is 1.5 tons. That's 0.375 tons per wheel.
Now we also know that tractor trailers run roughly double passenger cars on tire pressure, but the wheels are also bigger. For that reason, let's assume that the amount of surface area of each tire in contact with the road is consistent across the two. That means that the tractor trailer exerts the 3.25 times the pressure with each tire compared to the prius. On top of that, it does this on all 18 of its wheels, as compared to only 4 with the prius. Finally, the average traveling speed is going to be lower for a tractor trailer, meaning it exerts this greater pressure in the same spot longer than the prius.
Add in the fact that the damage done by pressure is likely not additive (3.25 priuses in a row does not equal the damage of one tractor trailer per tire), and it's easy to see that tractor trailers are the big wear and tear on roads.

aaaaaaahhhhhhhhhhhh I want to buy this!!!! But alas I cannot afford it at present, well it depends on if I get a 3DS next weekend or not. But having used the demo of Outlook I love it, much better then Mail IMO.
If anyone knows of a cheaper price then around �160 in the UK let me know cause that's the best I've found.

I'm running Panther on a G5 with multiple user accounts. When my wife opens a PDF document from the web it automatically gets saved to her desktop. Her desktop is getting just a tad crowded. I've tried searching "help" in acrobat reader (latest version) but for the life of me can't find anything that would automatically save to her desktop. BTW, when she does click on a PDF doc the screen that comes up defaults to "open" with and not "save". We are using Mozilla as our browser if that makes any difference. Any help would be appreciated. Cheers

And cut what?
Medicare fraud
Defense spending
Reducing the ridiculous layers of federal, state and local government
Corporate and farm subsidies
Welfare fraud
That's a good start.

I'm ashamed I work for them. I've always considered Target the "good guys" Wal-mart but the more I get a taste for their corporate side (retail as well as pharmacy) I'm less impressed day by day.
I'm sorry.
I worked at that hellhole for 3 and a half years and it went towards the crapper with each passing day. I went on leave of absence for school, but didn't come back over the summer due to me having an internship elsewhere, and they sent me a letter telling me to either quit or come back, so I said goodbye.
Their business practices, while better than Wal-Mart, are nothing to be proud about either. Maybe if they spent more time improving the shopping experience and less time high pressuring customers, err, guests, for those god damn target visa cards, loss of DVD sales wouldn't be a problem

Interesting. I don't have a degree, dropped college, not vegetarian and I don't wear designer clothes or read newspapers.

So many of the switchers are college kids. A few
months ago they had an article about how the
market share in college is really falling more toward
mac, more than ever before. Apple is getting them
young, and that will pay off in the long run. I got
my first Mac when I started college and now that
I finished, I got a new one. The new laptops have
made a huge dent in this age group, so that is what
a lot of this whole market share increase is caused by.

Apple Bitch notes (http://www.applebitch.com/2011/04/25/mac-os-x-10-7-lion-dvd-appears-on-amazon/) that a new placeholder (http://www.amazon.de/Apple-Mac-OS-X-Lion/dp/B0047CQ0ME) has appeared on Amazon's German site suggesting that Apple will be distributing Mac OS X Lion on DVD when it is released later this year.A listing for the latest version of the Mac operating system, OS X 10.7 Lion, which is due for release this summer, has appeared on the German Amazon website. The significance of the listing is that the OS is apparently being offered on DVD, rather than on the USB thumb drive, upon which Apple had begun to offer the Snow Leopard OS with the purchase of the new MacBook Air models last year.No price or availability date is given on the listing.
Amazon's site is a rather frequent source for product speculation given the company's tendency to post placeholders based on rumor in advance of official release information, and Amazon's German site seems to be one of the most active of Amazon's regional arms in this regard. Consequently, we hesitate to read too much into this speculation and are posting it on Page 2 primarily for interest and discussion at this time.
The distribution mechanism for Mac OS X Lion is certainly up for discussion given recent developments in Apple's hardware and software offerings. With the redesigned MacBook Air lacking an optical drive and proving to be a popular notebook for consumers, Apple's shift to a small USB drive for backup software on the machine has led to speculation that the company could adopt that method entirely for Mac OS X Lion distribution.
In addition, Apple has been delivering developer seeds of Mac OS X Lion via the company's new Mac App Store, which launched in early January. Consequently, it seems likely that Apple will at least offer the option of Mac OS X Lion as a download purchase through that platform.

I'm embarrassed for him at the moment, for the way he's acting like a spolit 10 year old kid, going on about Obama's birth certificate and college degrees. Has he got nothing better to do?
no, he doesn't. and thankfully it should mean that he'll have no chance of getting anywhere near being President.

You know, I would love an Apple phone as much (or even more) than the next guy, but something occured to me this morning...
All this talk, all this hype. If/When the iPhone comes out, most of you are gonna flame Apple for releasing such a POS. I'm already vommiting at the thought of how many posts will use the overused phrase "underwhelmed."
You will be underwhelmed my friends, I promise.
Also, to stay competitive in the mobile phone hardware market, you've got to release new hardware, with new features, at least every year, if not twice a year. Apple seems to be so slow getting out of the gate on this one that I wonder if they could do that. I mean, look at quickly they updated their notebooks to Core 2 Duo. Oh, that's right, they haven't.
Can Apple produce and continue to innovate a product every 9 months?

No PPC version... man, thats going to hurt sales somewhat. Adobe should remember the mass of Apples customers are PPC users, and most people still have machines around 5-6yrs old. Cutting them out the loop is harsh, not to mention those who own newish G5's.

Not sure what all the fuss is about the backlit keyboard... I don't think I ever found that feature to be useful on my MBP.. I guess if you type "pecking" style it's pretty useful..
On the 11incher I would love to see:
1. SD card slot
2. 3G or 4G
Otherwise some incremental improvements on memory, cpu, battery life, would all be great!

I downloaded it and tested it out a bit this afternoon.
First thoughts, Voice is real tinny sounding and not the easiest to understand.
Downloading maps was not a problem in the city at city speeds, on the highway that's another story, with in a couple miles the map ran out and never really did catch up till I got off the highway about 10 miles later with a full signal 3G connection.
The interface is nice and is very easy to use. Maps are good turn by turned was flawless. Checked out how current the maps where by going through a new subdivision only about 2 months old and it found all the street names no problem.
