I love our Apple Powerbook G4 15"...Apple have replaced these with Macbooks now I believe and (as with all things Mac)they can be expensive...but it's always worth looking round for a bargain...ours was a PC World ex-demo model with a full Apple guarantee and it was less than half original price. The learning curve from PC to Mac has been steep but well worth it IMO. If you do make the change go for one with Airport Extreme and a Superdrive if you need wireless connectivity and a DVD burner.
Plus, Apples always look so much nicer than PC equivalents
