i've used briefly the old macbook pro (2 years ago) and i liked it alot. now i am thinking about saving up to buy a new mac book pro (by christmas) does anybody know if there will be a refresh coming soon? okay that was a broad question thats not too relevant to my real question. my real question is will me buying a macbook pro without the ability to swap out the battery be bad? i mean what if 2-3 years down the line something happens and i need to swap out the battery for whatever reason.. how would i go about doing that? my other question is, since currentley its a 200 dollar difference is there anybody who owns a 13 inch macbook that currently feels like they should of paid an extra 200 and get the 15? i mean i'm thinking about it.. same specs.. only a 2 inch differance? is it really worth 200 dollars for two inches? i've seen and used a mac mini 9 (9 inch screen) with mac os x on it and the webcam app window was too big.. if i bought the 13 inch would this be a problem for me? does it come close to taking up the entire screen? lastley how long does the battery last with the brightness all the way up? i know the old macbook pro i used to have it would last about an hour and a half totally bright. and could last up to 3 hours when it was dim.. so whats the real battery life like? and one LAST question. is there a way to have gps tracking as an add on (usb or some other way) so if i was traveling in a car i would know where i was going? .. i know i could buy a gps, or use my iphone but i was just wondering.. i've searched and didnt find much.
