I'll second the N9.. A great phone! (had a N900 before). Eco-system is small, but that may not be a problem as there is less sh1t to download!

OK.. (wired devices.. NOT wifi!)

1 x Linux server
1 x MythTV server
2 x Myth Clients
2 x desktop machines
2 x IP IO devices (relay and input for heating/house control)
1 x Ehternet to 1wire (temp sensors)
1 x NAS box
5 x VoIP phones
1 x Workshop PC
1 x Backup PC
1 x Arduino heating controler
18 devices..

Wifi devices.
1 x iPhone
1 x Samsung GS2
1 x Nokia n900
1 x Achros 70
2 x netbooks
2 x laptops
2 x Noxon Audio media devices
10 devices

Grand total: 28 devices

Two things that have me wondering...
1) Any wonder our electricity bill is so big?
2) That is probably why we've run out of IP4 addresses!
