I use all kinds of computers, at work we have PCs with XP which isn't so bad. At my home pc which we rarely use I have Ubuntu Linux. I'm not too into computer stuff, and The Boy set it up for me, but it is used pretty similarly to XP. Then we have our lovely laptop, which is a Mac. We're currently lusting after a MacBook Pro, but haven't gotten it yet. The Boy is a Mac Fanboy so we have all things white and shiny. We just got Apple TV too which is sweet but the remote controls look like little ipods so it can get confusing.
Anyway, Macs are really user friendly, once you get past the initial learning phase. And you can get all your Microsoft-compatible programs for it so it would probably be ok to network into your work system. We have Excel and Word on our laptop, I'm still getting used to finding all my usual menu items, but it isn't so bad.
