The Mio A201 looks like a nice PDA (Bluetooth but no WiFi, and perhaps a less powerful processor than the very newest models), but the basic price in your link excludes software:
"This PDA is sold without any bundled mapping software which allows total flexibility in selecting
appropriate software for your particular application."
But then this package looks a very good price (£255.28 (£299.95 incl. VAT)) if you can stretch your budget. Anyone know how this software compares?
