One of the advantages of a chunky chassis is being able to accommodate a big screen, at least in standard smartphone terms. At 2.6inches corner-to-corner I found it roomy enough for everyday use, though I wonder whether the 240 x 320 pixels might have benefited from being upped to 480 x 640.
But it's inside the casing, in terms of both software and hardware, that Asus really makes me smile. For a shade over £300 you get a Windows Mobile 6 device with HSDPA support up to 3.6Mbps, as well as tri-band GSM with GPRS and EDGE for your mobile communications.
You'll also find Wi-Fi built in, and Bluetooth of course. And there's a SiRFStar III GPS antenna. Now, admittedly, there is no sat-nav software provided with the P750, but here's where I make my first mention of the bundled software on this device.
There are two utilities for using the GPS antenna. Location Courier lets you send your position to up to five recipients at a time as part of an SMS message, and Travelog captures your GPS footprint as a KMZ file. This is the file format accepted by Google Earth, so you can record a trip then drop it into Google Earth complete with self-saved POIs.
As for performance, the 520MHz Marvell PXA270M processor might not be one of the most widespread in mobile devices, but it seemed to zip along well enough during testing.
Battery life was really very good too. I asked the P750 to play music non stop from a microSD card with its screen forced on. It shaded over 12 hours which makes it the best Windows Mobile 6 device I've benchmarked in this way - and I have benchmarked a few, I can tell you!
When it comes to memory the 256MB of flash and 64MB of RAM aren't that wonderful. But the microSD card slot on the right edge of the casing supports SDHC which means you can add comparatively vast amounts of memory to the P750 if you have the desire to do so.
