Well, we're doing it.
Switching.
I bought a G3 iMac for my son off of ebay for $250, should be here by the weekend.
Ordering my wife a new iBook in a couple of weeks, her work finances PC purchases for 2 years interest-free, so we're waiting for that paperwork to clear.
My powerbook will have to wait awhile...but those 2 machines will eliminate Windows from this house as all my computers are x86 running some form of Linux.
