Question: Should I buy the iPad 2 and save $100?
Answer: Probably not.
The newest iPads feature a Retina Display, an enhanced back-facing camera and integrated voice dictation, but even if these features don't appeal to you, saving $100 by purchasing a similar model iPad 2 is probably not the best decision.
The iPad Mini 2 has all of the features of the full-sized iPad at the same price as the iPad 2, making it the best iPad for those on a budget. And for those who want to save even more money, Apple is continuing production on the original iPad Mini, which is priced at $299. That's $100 cheaper than the iPad 2 for a tablet powered by the same processor. The original Mini also has better dual-facing cameras and supports Siri. A Buyer's Guide to the iPad.
So who should buy an iPad 2?
Good question. At $399, the iPad 2 is for anyone who absolutely wants a discount on their iPad, but absolutely does not want the smaller "Mini" version. I would advise playing around with the Mini before making a final decision -- it is surprisingly easy to use despite its smaller size. And even then, checking around for a refurbished or used third or fourth generation iPad would be a better route to follow than buying the iPad 2.
