Everybody's talking about the new MB and MBP, but in fact the MBA is overdue for an update as well. Myself, I predict a minor update and a price cut: model 1 ($1599) 1.6GHZ penryn LV (17W) 120GB HDD model 2 ($2199) 1.83GHZ penryn LV (17W) 128GB SSD CPU: at the time of the MBA release, intel did not have suitable processors for apple's plans, hence the custom made C2D solution for the MBA. the LV-penryn would be a definite improvement - practically the same speed but heat issues would be eliminated and battery life improved. SSD: the cheaper model will have the 120GB drive used in the ipod classic and the SSD drive will be upgraded to a 128 GB version. display: although it is unlikely, the MBA could see a high-res display, at least as an option - e.g. a backlit-LED WXGA+ display as seen in the lenovo X300!!! chipset: it remains to be seen if the MBA will keep its intel chipset or also switch to NVIDIA. i personally don't think apple will make that change now since it would involve a major architectural redesign What do you think, will there be an update announced on Tuesday and what do you expect?!
