If you're one of those people (like me) who absolutely have to have the biggest and the best version of everything possible, then get ready to break out your wallets -- the biggest and most expensive iPad is now available the Apple Store online, topping out at 128 GB. The Wi-Fi model sells for $799, while the Cellular version with LTE support (your choice of AT&T, Sprint, or Verizon) sells for a whopping $929. Buying the AT&T model results in a 1-3 day ship time, while 3-5 days is the wait for Sprint and Verizon models.
