I have an iBook. Though I mostly use it instad of my PCs because of portable convenience, not because I'm a mac-head. I sortof quit using my desktop when I got my PC laptop, but the laptop battery only lasted abotu 45 minutes when it was new. Not very useful. My iBook lasts over 3 hours usually, which is usable. I'll probably get a PC laptop with much better battery life someday, and am not sure if I'll continue with he ibook at that point or if I'll be back to the PC again because more of my software runs there that I can't use on the Mac. I can' tpost pictures to Myspace from my ibook for some reason either, which is annoying. I shrink them in Photoshop and then MySpace's FLASH-based photo upload tool still says they're unacceptable for some unknown reason. If anyone has a solution, I'd love to hear about it.
