I'm still holding off buying another OS capable GPS simply because of the hopelessly restrictive licensing requirements of the OS. The GPS market is a rapidly developing one, but the OS maps are not transferable between devices, so if you want to upgrade your device, you will probably also have to purchase another set of OS maps, at enormous expense. In my view, the OS is severely limiting the use of GPS devices, and their licensing conditions must be changed to allow free transfer of the owners maps to a GPS upgrade.
The OS map system is the bug-bear of all off-road systems in Great Britain and there is no way around it as the data is proprietary and OS has excellent lawyers! however in the long run buying the full range of 25,000 - 1 maps is the only answer and makes this (and other similar products) VERY expensive.
Is there a more recent review - it is worth re-visiting - some piece on all the mapping formats would be good too - currently (May 2011) Amazon sell this device as the "plus" with Li-Ion battery etc and 1:50K for GB loaded as well as basemaps mentioned for £309.99
Also why are digital versions of maps so expensive? - production is very cheap onto an SD card (which is encrypted) - do a review get into it!!
