I for one would love "always-on" but I'm limited in Ireland ;

1. Limited 3G coverage at a very high price and major bandwidth capping & throttling.

2. Work network uses Cisco LEAP (any updates if OS2008 has LEAP?).

3. Limited constant free wifi coverage, (there are plans to have Dublin coved with "free" wifi starting 2008/9 so with the Irish Government/Country council doing it will be finished by 2025).
