I would like to upgrade form my current iBook - as it just doesnt seem to be cutting it as much as i would hope. I would like to buy the MBP - but not going to as I know a revision is in the works...but I dont want to buy the first revision as most first models have some kinks to work out. So I wanted to know what some options would be.. 1) wait, and somehow upgrade my ibooks power/ram? 2) buy a $600 or so pc for the time being 3).... your ideas? thanks.
