That's right folks, if you have been eyeing the O2 Xda Atom then there are a couple of reviews available on the Internet now for your reading pleasure.
Try loading the pocketpcthoughts.com or the osnews.com websites for a couple of articles with plenty of comments, screenshots and pictures (actually more than I would like to see if I were in a dial-up connection - the OSNews articles is a bit lighter).
In all aspects it looks like a nice media device, coupled with PDA and phone functionality. While Pocketpcthoughts.com don't say anything about the Bluetooth software, OSNews.com confirms it comes with Bluetooth stereo functionality (when loaded with the latest Windows Mobile OS version available from O2).
Pocketpcthoughts.com says the battery life is just mediocre, and the device is actually expensive for what it is.
I recommend you reading the full articles in both source, if nothing else, to have a look at what kind of functionality mobile media devices are offering now.
