EDIT-- It probably helps that the MBA has a higher pixel density screen and resolution.
That said, the ultrabook market is still in a weird state. I looked at all of the major vendors and no one really had the ideal combination of components yet. Once you can get the x230 with higher res display and a multi-core CPU, it'll be an ideal machine.
The only ultrabooks I can find with high res screen at the moment are either made by Asus or Sony. I've heard good things about the Asus UX31/32, full HD IPS displays (1920x1080) in a 13.3 inch laptop. A 12 inch laptop with 1600x900 would probably be ideal for me.
Even the cheapest comes with a dual core processor, though, so you can share your memory among 2 cores and an integrated graphics engine. Progress it ain't.
1024x768 -> 1280x768 -> 1366x768
but the trend reverses at the high-end: 2048x1536 -> 1920x1200 -> 1920x1080
Apple's 2880x1800 display is an exception, but so far the rest of the industry doesn't seem to be trying to imitate it.Real keyboard + 16:10 hi-res, high quality display and real thinkpad (IBM era) build quality and I would be willing to pay north of $1500
I pull out my old T42 from time to time and it's so relaxing to code on such a screen ratio.
I've been trying to grab a 4:3 (1400x1050) T61 for a while off ebay as they're cheap and upgradeable to a reasonable spec.
Unfortunately I can't seem to find one :(
Edit - I just checked eBay and searched for "T61p". I found:
* A 4:3 T61p with an incorrect description for $500. That seems high.
* A 4:3 T61p missing its palmrest and other parts, auction only.
* A T61p in a T60 chassis with a QXGA panel, SSD and other upgrades for $1300. That sounds high unless you've tried to find a QXGA panel; they're over $400.
1400x1050 14.1" !
The ones here tend to be broken.
(I actually wanted a 15" screen to replace my 15" T61 but the current 15" laptops are so frigging huge with so much wasted space that I had to downgrade.)
