The 6820 is Nokia's business phone. Its previous incarnation -- the 6800 -- was heavily criticised for not offering tri-band or Bluetooth; both of which have now been remedied. For something the size of a regular phone, we can applaud Nokia for shoe-horning a full Qwerty keyboard in.

Data input is one of the biggest issues many people have with PDAs, and while stylus handwriting recognition and Graffiti dont take long to learn, they can be difficult to master, and cant compare to typing on a keyboard.

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

Plenty of modern phones support email, of course, but what always made BlackBerry special was its push technology. With this, you don't need to dial up to collect your email: just sit back and wait for the messages to come to you. Wherever you are, if an urgent email comes through to any of your email addresses -- and the 7100v supports up to 10 -- you can act on it instantly.

The personal digital assistant (PDA) industry has experienced its strongest recorded first quarter with 3.4 million shipments worldwide according to analyst, Gartner.

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.

Learn to type faster and more accurately

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.

The past two years have been littered with attempts at combining a phone with a PDA. The first was O2 with its XDA (January 2003, page 41) - an excellent first try, and one that will be revised this month.
