I desperately need to get a new computer (currently still using a rev a iMac). Of course part of me wants to get as good a computer as possible, as I intend whatever I get to last for years. I had been thinking of getting a new iMac whenever they are updated, but recently I've been thinking about a macbook instead. Of course the macbook would be a bit less powerful, but my needs are pretty modest. I mostly use my computer for websurfing, email, chatting, etc. Nothing too intensive. I probably wouldn't carry it around that much, mostly this would a desktop replacement, but with the added freedom of not having to be chained to my desk. So my question for any of you who are reading this is what do you think of a macbook as your main (only) computer. Do you think it will be OK to use for a few years at least? How about the screen size? Is it too small for everyday use? I appreciate anyone's thoughts and experiences with using their macbook as their main computer. Thanks.
