You are trying to decide between a Wifi/3g/LTE enable iPad or standalone Wifi one? Sure that extra $129 for a cellular data equipped data can be use for something else. So here is a nice infographic that may help you decide.
See only a tiny 6% of all iPad session use involve cellular data the rest is done over Wifi. So if I was you I will stick with the Wifi only model unless you spend a lot of time in the road in which case you may even tether it to you iPhone (for free if you know your work around)
If you are looking for a powerful mobile device that can do most task a laptop can but is cheaper, lighter and easy to use then you should not waste your money purchasing a tablet.
You should buy an iPad. Wait isn't the iPad a tablet? In my honest opinion the iPad is no more a tablet than the iPod was an mp3 player. The iPod was technically an mp3 player but it was on a different level.
You had the iPod then you got all the others iPod wannabe collectively known as mp3 players. The iPod was something you enjoyed using and kept for years. The mp3 players was what you bought when you needed a cheap something for that office gift exchange.
The same applies to the iPad. Technically the iPad is a tablet but is just so above anything else in the market. It just don't make any sense to put all the other tablets on the same level.
Apple dint needed a new iPad the iPad2 was perfectly capable to take on any tablet on the market and even ones that had just been announced. But Apple announced the new iPad yesterday and in doing so it cemented it position not only as the market leader but the market owner. And I don't see that changing anytime soon.
So do your self a favor and buy an iPad even if is just the old iPad2 you wont regret it as you will do by buying an iPad wannabe tablet.
