White 64GB LTE Verizon iPad
Why? Verizon LTE is way superior than AT&T. (Superior in that they have more coverage, more experience and they have a 1GB for $20 plan with free hotspot)
White because IMO white looks better with electronic devices. Plus it reflects light meaning that it won't absorb the light from the sun. (Reduces the temperature of the device which in the end extends the battery and performance [if a device is running hot I am assuming the frequency of the CPU would drop])
