MrMacPlus, you are totally right about Vista - but don't forget that I'm here for the same reason as everyone else. I actually did a lot of my work this semester on my Mac Classic, as much as I could do because its eminently better for essay writing and note taking. When I got my new thinkpad, it would have cost $50 extra to get XP Pro, and since I have many XP discs (I have been doing PC repair for quite some time) I figured I'd get it with Vista and downgrade later. Anyways, I have Vista basic with almost everything turned off and my machine works very, very fast and does everything I want it to, so I've never been compelled to get all the XP drivers, etc. and do it all over. I do a lot of multi-channel sound recording, and Vista on a Core 2 Duo works much faster than my P4 3ghzHT did with XP, so I really have zero qualms other than startup time, etc. However, I'm getting bored with Vista basic so I may try Windows 7 until college starts again, and then move back to XP for the start of the semester just to be safe.
So I do like the PB5300cs, most because of how it looks and its size, but i'm forced to conclude that it doesn't have the simplicity of my System6 Classic or my System 7 Color Classic or the power and ability of my Core2 Duo Vista machine. It kind of lingers in the middle, so I don't know how much I'll use it. I'll probably use it as a backup laptop and get that Wifi A card.
