You may want to check that it has got a GPS receiver built in.
On the face of it, Teds' find is ok BUT.....
The 1010 tablet -There is one which HAS a SIM slot and one without.

NEITHER of these '1010' tablets have a gps receiver
so if you want real time info, you'll need a data plan in each country which will become a nuisance and big $$$ over time provided you buy the one which has the SIM card slot.

Initially I too was looking at a windows tablet but those I found did not have a GPS receiver built in.
And thinking about it, I did not need Basecamp.

Android comes up trumps in terms of speed and everything else IMHO.
All my waypoint .gpx databases have been converted and load up beautifully on MapsMe ( Free) App. which uses OSM data. The maps scroll as you move along. You do have to download the maps before you go but it can operate with those maps being on the external micro sd slot which is bonus in terms of space saving. Our planet takes about 28GB - don't ask!

For practicality, I chose a Samsung 10"tablet which does have a built in GPS receiver and a SIM card slot in case my phone fails.

I used to have MapSource (discontinued) running off a usb stick ( which I have used in web cafe an dother peoples' notebooks and am about to see if Basecamp and Garmin Express will do the same for the heck of it!
Sorry Ted!
