Solid Workhorse
Basic PDA that has done what I needed it to do for many, many years (thought for sure I got it pre-2000s but Wikipedia suggests post-2001). If your needs are more utilitarian and you don't feel the need to buy the "Latest Greatest" every year or so, this puppy will do for you. I've got a handful of apps on it but would still consider it useful even without them. Get the "Kensington PDA Protector Hard Case Blue Ice Designed for Palm Vm505 M500" for it!
