While not as detailed as some of the others it is still an interesting read.
"If there's one thing Dell does well, it's give you a lot of bang for your buck. The X50v is $499, a whopping $150 less than the iPAQ hx4700.
As I mentioned before, the X50v has a smaller screen that its chief competitor, and the iPAQ has some additional features, like a trackpad, flipcover, and larger battery. But anyone thinking about a VGA Pocket PC must think hard about the X50v. It's a solid device and an excellent value."
