yay! I've finally managed to re-retire the old mostly broken laptop after going on a spending spree this evening and getting myself a nice shiny new macbook and a shiny new 24" iMac which is being delivered tomorrow. You don't realise how much you miss a good computer until you are stuck with a really bad one for just over 2 months.
I was at my cousins house earlier this winter and he had a newer mac (OSX) and it could right click fine... It was actually much nicer than Windows XP, I only had a few minor annoyances like the close/min/max buttons being on the left. The other cause of frustration was the hotkeys (apple instead of ctrl, which is in a different location, but some applications DO use the other key).
right click is perfect on an imac. no rightclick on a macbook, but you just use ctrl + click instead. it's so much easier than windows though, especially than windows 95 which is what i've been using for the last 2 months
