Yep, I would think the next G eVU will be much more in line with the 3G phone world -- but with a larger screen. My LG phone has ~12 TV channels for live TV anywhere I can get a signal the ATT service is offered. It's great for all that time in airports and cabs.
However, I really hope cell phone use is not allowed on board flights as there are too many loud mouth arseholes who will be shouting in my ear. Email and web access is fine and fast enough for almost any biz activity. EDIG's eVU screen size will work well with email and web views -- I trust the guy next to the 12 yr old kid will not be viewing his "Jenna" collection of documentaries.
