K guys, for the longest time i've been a windows fanboy, but after much convincing i've decided to go with a new macbook. here's the problem, and i know this has been asked plenty of times, but should i really wait for the new upgrade in the macbook? if so then why? i've heard rumors of the new ones having LED backlit displays which would increase battery life. i currently own an hp laptop and want something smaller and lighter. i don't really need the computer now, but it would be nice to have. are the new changes that significant for someone to hold off right now? what are the major changes that the new one will have? (ie...battery life? run cooler? same design/size?) please help me decide. i almost purchased one last night. but if ya'll think i should hold off for now then i will. thanks in advance for the advice guys.
