The myS-7 from Sagem is the company's first foray into the smartphone market with Microsoft's Windows Mobile operating system. It's a little larger than the Xphone II but this marginally wider neck means that keys are just that tiny bit wider, and when your main mode of input is the keypad this tiny extra can work wonders.

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 new Nokia Communicator  unfortunately evokes early '90s mobile phones: it has a long body, small display and is not something you could slip into a pocket. Closed, the 9500 is monstrous, but when you open its sideways clamshell design the 9500 comes into its own.

This is the second Smartphone we've reviewed (O2's Xphone, March 2004, page 55) but, unlike the Xphone, the Motorola MPx200 features a clamshell design. Smallish, black and sleek, the MPx200 is a Tri-band GSM 900/1800/1900 phone with GPRS which enables email, SMS, MMS and WAP capabilities.

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.

The N-Gage is as chunky as a phone, but when you use it with both hands to play games the N-Gage shines. The 3D processor is good, so you can get some reasonable depth-of-field gaming on the device.

You can stick them in your pocket or you can hold them in your hand. Six smartphones and phone PDAs reviewed

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.

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.

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

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

The AS2400DW picked up the Labs Winner award this month for several reasons.

A funky set of  Bluetooth headphones. Connect to a variety of audio sources or use the built in MP3 player.

Acer was one of the few big name manufacturers that were able to meet our stringent pricing criteria. The submitted notebook, the TravelMate, is not a so bad overall, but it couldn't win out against the smaller manufacturer's abilities to get top components at short notice. Where Acer excels is in after-sales support.

Last month we reviewed Microsoft's Bluetooth-enabled keyboard and mouse (January 2002, page 52), and at $399 we deemed it more worthy as a Bluetooth starter kit than a wireless keyboard and mouse kit.

Part 2 of our VoIP products and services roundup includes: MailVoice, LetsChat, Netgear TA612V, Netcomm V40 and Octtel gateway.
