Powerbook Duo 230
Duos are great. They are small and you don't have to pack around unessesary things like floppy drives.
This duo was an ebay purchase.  I bought it along with a duo 2300c.   It needs a battery and seems to have a hard drive or software issue.  It starts up great then makes some noises and boots to a disk with a question mark.   I removed the hard drive and put it in my 520c and it worked fine. then I put it back in the duo and it works fine for a while then dies again.  I wish it was perfect but it is very old.  I'm just happy it boots. 

I will add a picture of it on when I take it apart and make it work again.
