"Mobile" phones come full circle. Cell tower coverage still isn't even sufficient for a lot of my use. Unless I'm at home or work, I almost never am in range of a wifi hotspot. I am very frequently not at home or work.
My employer has "roaming" wifi. I can walk around, change floors, change buildings and not lose connection. I don't know how they do it. It's very cool.
Compared to... I was contracting at AT&T Wireless for a few months. Worst enterprise IT I've experienced. Getting a desk phone to work was near impossible. No one could access their voicemail. No voicemail - email bridge. The in-house chat/voice conferencing didn't work (stutter, dropped connections, couldn't login). You'd lose wifi connection walking down the hall, requiring full reauthentication for everything (signin, VPN, db connections, etc).
