Hi, So I have a 15.4" SR baseline MacBook Pro purchased last year, cost me $1999, but I sold the free iPod for 180$ surprisingly so the expense amounted to $1820 I suppose (forget the tax for now). I have an offer for the MacBook Pro for $1700. Seeing as there will be new updates soon, my current machine is sure to depreciate quickly (well, I'd have to sell it for at least one hundred dollars less, I suppose). I wanted a smaller notebook - I already have a 24" iMac at home and I realize I exclusively use the MacBook Pro for taking notes in class and internet surfing. It's crucial for me to take notes on - wouldn't be able to survive classes doing it with a pen and paper! Anyways, commuting every day with a smaller and lighter notebook would be nicer and the smaller size of the laptop would allow it to fit easier on the tiny tables... Anyways, I like keeping up with all the new, cool stuff that comes out. To me, I'd rather upgrade more frequently than once every 4 years, because at the end of 4 years, the laptop is practically worth nothing, yet after a year, it will still keep its value. So the question - do you think it's worth it to sell the mbp for 1700 and then pay around $300 (with tax and all...) to upgrade to a new machine (that suits my needs perfectly)? At the end of the day when I get home, I don't even use a USB key to transfer my notes to the iMac...I do it all wirelessly. I really have no use for an optical drive as I already have it in the iMac. The MBA looks really great and would be more practical for me than the pro. So, is it a good move? Thanks!
