Wider than a normal phone and encroaching on PDA girth turf, the BlackBerry 7100v is both a capable phone and a capable PDA.

The Sony PEG-NV70X Clie marks a welcome shift in the PDA landscape from the Pocket PC, with a few firsts up its sleeves.

The new Sony Ericsson P910i is the only true phone/PDA hybrid on review in this roundup so aesthetically it marries some of the largeness of a PDA with the slimness of a phone to end up with a unit that's just right: it's not too big and not too small.

The XDA (January 2003, page 41) and the XDA II have both done well in PC Authority reviews before, but our main complaint has been one of size: the XDA's are normal PDAs, but big phones. The XDA IIs still keeps a large touchscreen, but the unit is slightly slimmer and thinner than the previous models.

The 650 really picks up where the 600 left off, and while it doesn't look too different to the eye, many of the changes are under the hood or subtle manipulations of the 600's design. It runs the new Palm OS 5.4 and has a much faster 312MHz Intel PXA270 processor, but the most immediate difference is the screen: it's now double the resolution at 320 x 320.

There's one thing that's immediately noticeable and annoying about the otherwise superb Xphone II: it's incredibly slow to turn on and boot up. We clocked about 72 seconds from pressing the power button to connecting to our service, with about a minute of that taken up by just booting the phone's OS.

The key differentiator with the PDA2k over other PDAs is the whopping 128MB of RAM in-built for media and files. On top of this there's a separate 64MB ROM for the OS and an SD/MMC slot for further expansion.

Never judge a book by its cover, they say, and nowhere does this apply better than to the Nokia 9210i Communicator.

Even if the Twinhead Efio! 2003CTZ couldn't hold its own with the big boys here when we benchmarked it, we were highly impressed with the unit's features and pricing, which countered its relatively low performance and rocketed it into the top three in the Labs.
