I have a PowerBook 160 for sale. I don't know what the education prices are currently (I didn't buy mine at an education price). My configurations is as follows
10 MB RAM
40 MB Hard Disk (I have AutoDoubler 2.0 Installed which gives you effectively 60 MB).
T/Maker Carrying Case.
Lots of share ware software as well as a few other commercial applications.
I haven't sent in the warranty card yet, so you would have a year on the warranty, as well.
I would like to get $2400 for it. If you are interested, make an offer.
