I'm converted to the iMac - but I run Vista on it with BootCamp.
Works perfectly - looks stunning - great screen.
Leopard is ok - I'm a NeXTStep afficionado so I love the finder, Entourage is nice with it's project focus, but Word and Excel ain't quite right on it. Running XP or Vista under parallels is great, but Safari occasionally renders things wierd (not its fault probably more the page optimised for IE).
The new keyboards don't have enough travel for me, so I'm using a Logitech one - no problems there either.
Decent machine, decent performance, looks the mutts - runs Windows if you want - it's all good!
Mind you, with a little creative patching you can install Lepoard on vanilla intel hardware, so you could always give that a go if you want to dabble in Mac without the hardware premium!
