I'm seriously considering replacing my WinXP desktop with a MBP 17" but have a few questions. I plan on using an external monitor when on the desktop (possibly a 30" ACD) but am undecided as to use the MPB keyboard or an external keyboard. I'm just wondering what others are doing. If external is the way to go - wired or BT. Any other considerations when using a MBP as a desktop replacement?
