Not sure why they didn't include the option of 4G as being an advantage of those Apple devices.
The size advantage of the Nexus 7 is great for mobility (honestly dislike carrying an iPad in my bag) but the majority of areas are not going to have wifi, hampering a bit of it's advantage.
I don't see inclusion of 4G on any tablet devices as a plus. It drives up the cost slightly more and it has never really made sense for each device to have their own cellular connection.
Most people who buy tablets are likely to have a smartphone so it would seem more appropriate to have tethering and use that one connection for multiple devices.
I realize that's a personal choice, but I currently own an iPad 2, Kindle Fire, 2 Kindle Touches, and I just bought the Nexus 7. I'd rather pay for one connection and tether all those devices to that connection than each one have their own.
I believe jaems33 is referring to the phone being used as a hotspot. I can, almost literally, watch the battery drain when I put my wife's Android phone in hotspot mode.
Also, there are more popular 4G data plans now, such as T-Mobile's "No Annual Contract Mobile Broadband Passes" that you can enable on-demand, only requiring once-year usage to keep the account active. I'm not sure if other carriers offer similar plans.
The experience of using a hotspot just plain sucks. That’s why it’s so stupid that hardly any notebooks include 3G/4G.
I used to think that has something to do with stupidly expensive and restrictive US data plans, but you have some decent ones. The situation in Europe is still better, though.
If you've already got a Nexus phone, you don't need 4G/3G on your tablet. You've got a mobile hotspot already. The Nexus Phone + Nexus Tablet + Nexus TV products fit each other very, very well.
