Pykmaze alleviates this issue and allows to transfer data from/to the device with any host. PyKMaze Abstract Geonaute Keymaze 500/700 GPS watch devices are shipped with a Windows-only application software. I'll see what they go for, then either bid on one or get a recon unit from Habdtec. If that's the case, then I think the 201 is worth the extra tenner, especially with the internal Lithium-Ion battery. I've read the specs and downloaded the manuals and I can't see any mention of connecting a 101 to a PC to view tracks on Google Earth or Memory map.
That Maplin one looks like the cheapest option, but we want a display screen so she can see how far she's run while running.
