A lot will happen, obviously. But as I'm in the market and have no real preference between the two (and both seem like they should last a very long time), I'm curious as to which one people think will be less obsolete in 5-7 years: the MBP or the MBA?
I was curious about the same thing and it was one of my reasons to go for MBPr instead of MBA.
MBA is in previous gen body since a while and now retina display has made it to macbooks, it will soon be on the air in the comming 1-2 years.
A retina display is a big leap which probably means a new body.
Retina mbp costs 2700 dollars where i live, mba costs 1400, i was getting 18% discount on the pro and 11% on the air, so undoubtedly went with the retina(500$ off!)
Excpect the resale value to go down by 15% each year, and the new retina mbp design is here to stay for a few years.
You will definately loose some money on both, but as air may get a physical refresh soon, it will loose another sum while retina wont.
But mbp retina body will probably not be here for 5 years either lol
Retina has a faster processeor and more ram better graphics. Its very very much likely to be alive after 5 years
And, my needs were simple too but simple basic needs may still use the bigger, better, high res screen, better and louder speakers, smoother playback of videos and movie due to dedicated graphics, more ram means more smooth working for the years to come, i7 quad core processor means faster interface, and 128gb in air is way too less, specially if you're looking to use it for a long timr.
If you upgrade the air to more memory and ram, you will come closer to the price of the retina one, bcoz of which the retina now becomes even more worth it.
Just go for the retina, everyone dies without their money in december anyways.
