Check out this unboxing video of the iPaq 614. Tracy and Matt of Tracy and Matt's Blog, have done a nice job with this unboxing video. The iPaq 614 looks to be about the size of the Palm Centro but of course runs Windows Mobile. This one doesn't appear to be headed for US shores any time soon.
Specifications quadband GSM, tri-band HSDPA, 520MHz processor, 128MB RAM, and a 3 megapixel camera.
