and 6 months later the vaio z will sell for 50% of $1900 and 3 years later it will sell for $300
I am in process of selling my 2008 macbook air for $699 right now. lol.
This actually works against the Mac. I got a VPC-Z122GX (retail $1799) for $900 two months after it was released. The store's regular price was $1499. It was being replaced by the VPC-Z13 (yeah, Sony updated the model in 2 months, and 2 months later they came out with the VPC-Z14). So the store marked it down to $1200 as a closeout. Then they mailed out a 25% off coupon in a special promotion for repeat customers, dropping it to $900. (I then sent in an old laptop for Sony's $300 trade-in program, so after all was said and done I paid $600 out of pocket.)
You will
never see markdowns like that for Macs. So your choice is a full-priced current Mac, a 1 year old model for 15% less, or a 2 year old model for 30% less, or buy used and pay twice as much as for a similar-aged
new PC. So yeah you'll get more for it when you sell it. But if you compare the deltas between paid and sold prices, you end up paying a lot more for the Mac (unless you bought a bleeding edge PC laptop).
Consequently, the specs on my 9-month old Sony Z blow away the specs on the current Macbook Air even though discounted 50% it's substantially cheaper than the Air. 2.4 GHz i5 vs. 1.86 GHz Core 2 Duo. 4 GB upgradeable vs. 2 GB soldered. 1600x900 screen vs. 1440x900. Dedicated nVidia GT 330M w/ 1 GB vs. 320M integrated. HDMI+VGA out vs. mini Displayport. 3 USB ports vs. 2. DVD-RW vs. nothing. Expresscard slot vs. nothing. Gigabit LAN port vs. nothing. The specs where the Air wins out are mostly inconsequential: 13.3" screen vs 13.1", 7 hr battery vs. 5 hr, 2.9 lbs vs. 2.98 lbs, 3-17mm vs 24-33mm, and all-aluminum construction vs. aluminum keyboard bezel.
The Macbook Air's screen is absofuckinglutely blow your ass out of the water STUNNING. It has little to do with its resolution, but its display quality, contrast, and brightness.
It's better than most PC laptop screens, but it's only decent - there are much better PC laptop and other Macbook screens out there (especially the old Macbook IPS panels). I do photo work on my laptops, and the Air's color shift with vertical angles was simply unacceptable. The Sony Z has the same problem (it's a TN panel too), but it's much brighter than the Air (I only raise it above 50% when outdoors - it's too bright indoors) and has better viewing angles, so I find it adequate. I really miss the IPS panels though, and probably would've jumped on the X220 if it had been out when I was shopping.
Apple seems to be the only laptop manufacturer who really cares about the screens. Theirs range from decent to stellar. But their low- and mid-grade models (including the Air) only have decent to good screens. That said, PC laptop screens usually range from sucks to decent. But certain manufacturers do put good to stellar screens on certain laptops. In my experience, these include Sony, Lenovo, HP, Toshiba, and Asus. You just have to be prepared to pay for them - don't expect them on the low-end laptops. (Except the original Asus netbook. That had a better screen than 95% of the laptops out there - LOL).
