well unfortunately if you have the deluxe version i dont think you can share the disk since the key is linked to your GPS receiver, and if you have the non-deluxe version it's a hardware key. i would imagine they have a way around sharing it.
the maps for any garmin device are said to work with GMPC (per their techs) and given this you will always be able to update the GMPC maps until some radical new platform comes out.
when i discussed this with them last week they also stated that given all the new android and windows 7 tablets that are coming out this year it would be "highly likely" that garmin will release a new, better program to replace GMPC, so i wouldn't worry!

now this is partially based on my discusion with him that the nav software on his garmin phone is far superior to garmin PC, and that phone runs on android, so obviously they are already looking to expand in different directions and that it may have just been too much effort to update the GMPC software, whereas killing it off and starting fresh affords them many more opportunities.
