To cut a long story short my Mum is very special (you'd love her) and disabled. It would be great to video chat when I can't be there. I have iMac/MacBook and I thought about getting hold of an iMac G4 which has an ideal footprint and angle-poise function for her. Basically in conjunction with a video-cam (plus Skype 2.0 as Apple require mutual dotMac membership for iChat), wireless dongle (which I have spare), a robust ergonomic wireless mouse and maybe Miglia TV mini - she can use it for video chat, music, and TV. G4 is before my time - any advice please on spec to cater for the above?
