Ok, nice, I do have MacBook Air 1.6 Rev A.... I'm pretty happy with it, untill I need to do Photoshop, large, "manymultilayered" file... whatever, but now, do I need to live with that ? No, I want to upgrade, maybe rev B, more likely strong MacBook 2.4 (new one) or even better, MacBook Pro 2.4. But now to the point...: My Air is worth half the price now (let's say £700), MacBook Air revB: £1,271. So: Add £571 to the upgrade. MacBook 2.4: £1,125 (+£425) MacBook Pro 2.4: £1,369 (+£669) But now here's the thing. To wait or not to wait ? Apple releases are ONLY based on speculations and rumors !!! No pre-announces, no time-line, nothing... and I don't like that . Anyway what would you recommend ? Did a research here and there, I'll probably go for the MacBook 2.4.. or wait, maybe Apple got a surprise in Jan. Pff . They should have something like a "swap your old for a new one" thing. At least for the same product line.
