My sister is considering getting a beautiful 24" iMac to replace her aging iBook G4, and as the resident Mac nerd, it's my duty to guide her. I suggested getting a wall mount and BT keyboard and mouse and create a truly awesome setup. She was intrigued, but now I need to know what is involved. The Apple Store says I need a wall mount and adapter, but does anyone have any suggestions/comments/tips on what I can do? How hard is it to install yourself? I really don't want a 24" iMac coming crashing down on the desk.
