The A201 is a very very average PDA, 312Mhz, 64Mb ROM, SD Slot only, no WiFi, etc, etc.. It would do the job though, but you can get better for around that price..
PDA - the TOP End DELL X51V PDA (624Mhz, BT/WiFi, VGA Screen, CF/SD Slots, WM5, 128Mb ROM etc) - £229 + delivery (free if you go and pick it up!)
Ebay X51V (New from a shop)
OR just a 416Mhz Standard X51 - £172.99 from
EBAY (Still BT/WIfi/CF/SD/128Mb/WM5)
TOMTOM5 Software, genuine, on SD Card = £99 from numerous online shops
And a GPS can be had from Ebay, I'd recommend a seperate BT jobbie, but you can go Compact Flash if you want.. depends on intended usage, these range from £40 - £70
Or if you want the best, you can get the TOMTOM5 Bluetooth GPS + Software for £175 from a number of places..
depending on what you want..
The Ultimate is the X51V with TOMTOM5 and Genuine TOMTOM BT GPS, this would be £229 + £175 = £404, but this is leagues better then the other PDA solutions you have been looking at.
Or a normal X51 + TOMTOM S/W and BT GPS = £347, still a much better PDA then those you've been looking at, and all genuine TOMTOM GPS/Software
Or cheapest would be the standard X51, BT GPS from ebay at £48 and TOMTOM software £99 for £319.99..
At the end of the day, any PDA with TOMTOM is going to do the SATNAV well, but as a PDA with WM5, you really want to be getting something with some power and expandability
1. ROM size is a big issue on WM5 devices, all programs etc are stored on the Flash ROM, the bigger the better, 64Mb is only just adequate, 128Mb is much more flexible, people are using SD cards to store some of their programs on, but this is much slower and has some issues with certain software, SD cards are best left for data storage, maps/music/videos etc..
2. WM5 is like Windows XP, it needs a slightly beefier processor, 312Mhz is really pushing it.
3. The Integrated GPS PDA's are a bit bulky depthwise, the GPS antenna takes up a lot of real estate, which is why sacrifices in CF/SD slots/Wifi/BT are always made.. having an external GPS (or CF if you want it physically attached to the PDA) you can replace this, or leave it behind if you want, I just leave mine in the car, since it's Bluetooth, you just switch the PDA on, launch TOMTOM, and it's all automatic, no faffing around.. when I take the PDA from the car, it's easier to 'pocket' being so slim..
