Im planning on buying an IPad 3 within the next few months. Ive done a bit of research (mostly YouTube videos and some information I located on the web) but wonder if any of you guys could direct me to a place that I could use to learn useful information about which variant to purchase. I just recently became aware of the ATT/Verizon variants. Im unsure as to how much memory to purchase, whether I should buy the 4G option and what apps I should look to buy. In regard the last question, I realize this is sort of like asking how high is up. Id like access to the internet of course, also mapping software (stand alone from the internet if possible), plus a reasonably competent office program (word processing and spreadsheet, both compatible with MS system computers). Thanks!
