I really think they're doing it the right way. Don't rush the PowerBook G5 just to satisfy the masses... We finally have a Mac worthy of the name G5, the Power Mac. If power's what you want, you can get it right now, in the form of a desktop. I have never thought of laptops as serious power tools. They're MOBILE tools, allowing you to do your work away from your desk, to a certain degree. But anyone who wants to do serious work (video editing, graphics, 3D, complex math, you get a desktop. Period. Anyone who has ONLY a laptop generally uses it for lighter stuff (word processing, email, internet, spreadsheets, music).
Sure, there are many PC "laptops" that use desktop Intel procs & have RAID drives and that kind of stuff, but honestly, does anybody actually lug these 10 pound "portables" around? And if so, is it just to play Unreal at a LAN party?
Notebooks are for mobility, desktops are for real power users. It's just not going to change. So, Apple, take your time making the G5 PowerBook, and make it unbelievably droolworthy, stable, and berautiful, because as much as I want it to completely obliterate anything on the Wintel market, I don't believe it is necessary right now. The 15" and 17" seem pretty powerful for what laptops are designed to do, and I'm sure would satisfy any of us until next year's revisions.
Just my ramblings.
