Hi Romingyak - Are you sure? As far as I am aware, you still need to use a windows based system to get all the funtions of Garmin Mapsource - I use VMware Fusion on my Mac to run Windows XP, and that gives me everything PC or Mac.

If you are using the new unit in a (four wheeled) vehicle then a PDA type unit is probably the way to go as people say, but on a bike a hard-drive (opposed to a flash/card memory) will skip and cause problems - it can happen in a 4x4 offroad too.

The ability to load other programmes into a PDA such as the UK O/S Memorymap is also handy, although I would say of limited use on a two inch screen unless you are simply using it to follow a preplanned route. And of course Memory Map is only of use in the UK...

A dedicated GPS unit is still my preferred way of doing it - the software/controls are usually more intuative, and there tends to be a built in robustness to the product too (dust and water proof always handy). Unfortunately ´the majority of the newer ´car´based units tend to have limited track log and long-lat etc abilities, being geared more to on-road navigation...

Also, touch screens will scratch if you use them in dusty conditions - although I use a camera screen film on my Garmin 2610 which works fine.

Sorry if that confuses the issue further? - some more to think about anyway!
