Query: DO NOT BUY!

I just purchased this as an inexpensive way to have contact information handy at all times. It's the perfect size--love the keyboard that slides out of view, and the display is easy to read. HOWEVER, the synchronization feature with its own software or with Microsoft DOES NOT WORK. I have called Royal twice and faxed them. I could hardly understand the person who answered the synchronization line, and all I got was a promise to call me back in a few minutes. Never heard back from them. I didn't pay much, and I got even less.
