Great choice for a first hand held.

I purchased the X51 520 a couple of months ago, as my first hand held, and have yet to be disappointed. The Windows Mobile system is very easy to learn to use, as are the features of this unit. It packs plenty of mobile power to operate lots of programs, and, with it's easily expandable memory, should last me a long time before needing to upgrade to another unit. Access to installed programs is fast, as well as wireless connection. The included features are also easy to use (wifi, Bluetooth). The button to enable/disable wireless is in an awkward spot, but doesn't pose a problem due to having to double click it to activate it. I did a lot of research before choosing this unit, and, for the price, couldn't find a more powerful, feature packed model.
