In the PC world, though, you know when new Intel stuff is coming, and you can be sure of PCs with the new stuff coming out soon after.
Apple may take months before upgrading to current Intel parts (quad core in the Maxitower, and Penryn in the laptops for examples).
Exactly - that's my point! =)
Still, I'm totally sold on Macbook functionality. I'm going to wait until the rumoured next July (?) update and then buy. I'm not so worried about a silver redesign; I really like the white. Plus, you could wait forever, gotta take the plunge sometime.
