Anybody here use an iBook with VNC to a PC?

After using my desktop G4 yesterday (for the first time in a while) I'm really tempted to get a iBook. You forget how amazing OS X actually is when you don't use it for a while!

I need to get a laptop, but I don't particularly want a PC. My problem is that the only piece of PC software that I really need to run developer studio (big problem!).

My solution would be to VNC to my desktop PC and do the development work from that, problem solved.

Does anybody do anything like this, if so, what is the performance like? That's my only real concern. I've done PC to PC VNC and the speed was fine, I'm just wondering if there's anything to be wary of with regards to the iBooks processing power.

Thanks.
