My brother is in the market for, in his words, a "portable word processor." He wants to be able to write wherever he goes. I suggested an old PowerBook. - He doesn't need anything fancy. Networking capability (or at least expandability) would be nice but not a requirement. Same for a CD-ROM drive: Nice, but not a requirement. - He needs to be able to transfer files from his iMac DV to it. Since the PowerBook won't have USB or Firewire and since the iMac doesn't have serial or parallel ports...? - He doesn't need anything fast. Or even with a color screen. A backlit screen would be nice, though. All he has to be able to do is type on it without it breaking down on him. So my question is... what would be the best options for used PowerBooks? Are some less flaky than others, or some that age better? Are batteries still available for any of them, and are they expensive? Would it be possible to get a really old PB for under $100? $75? What would be the best word processing software for one of these puppies - Word 5, old version of ClarisWorks? Thanks for any advice.
