Dell Axim x51v. I thought it was supposed to be fast, with that supposedly fastest-ever PDA processor, and could do a lot.
I thought I would use it to write notes when away from comp, browse work email when away from comp, make spreadsheets of the many things I need to stay organized on with MS Excel, use as mp3 player, watch videos, add GPA software and CF-based hardware and have GPA, read ebooks, read pdfs, etc.
File management was terrible. Adding and deleting programs was terrible.EAlmost everything I tried to add was a hassle. Video codecs were a hassle. Calendar/email barely better than doing without. Battery ran out all the tim,. so I got a big bulky battery.
Never got publically available GPS maps to load, so never sprung for GPS sensor.
Overall, was passibly fair at a few things, and not really good at anything. There were a lot of axim enthusiasts then, and so I at least could sell off all my axim stuff.
