Maybe you won’t have to fight to get your iPad 2 at launch from an Apple store after all. Beside being available in AT&T, Verizon and its own Apple stores, iPad 2 will also be available online and in the stores at Walmart but currently showing as out of stock (although at the time of writing, only the 3G capable version is shown as available for purchase). Anyway, it is really good that there is yet another venue to get it. Both black and white versions will be available.
The prices are the same, the 3G version starting at $628 while the WiFI only starting at $499, depending on the configuration.
The AT&T data plan are $14.99 for $250MB or $25 for 2GB. Verizon has several data plans available from $20 for 1GB allowance, $25 for 3GB, $50 for 5GB and $80 for 10GB. Believe me, get the WiFi only and tether through your smartphone, is soo much better / cheaper.
