I've been tossing around the idea of getting a new Intel Powerbook when they come out next year, and an idea occured to me... A lot of people complain that macs aren't very upgradeable - sure you can swap out the HD, memory, disk drive, etc., but you're usually stuck with whatever processor you started with. Wouldn't upgrading the processor be significantly easier when you're starting with the most widely used processor on the market? Is this potentially going to make processor upgrades as painless for mac users as they are currently for PC users? I realize it's all pure speculation at this point, but am I totally off base? Or do you think that the Intel chips will mean more upgradeability for macs?
