I donโt recommend that average iPad Air owners upgrade to the Air 2. But what about the vast majority of iPad owners who own older models? Thatโs a different story. If you have an iPad 2, 3 or 4, the new Air 2 will make a big difference. Its thinness and lightness will be a dramatic change, and it will be faster and more fluid. However, hereโs the catch: Upgrading to last yearโs iPad Air would have pretty much the same effect, and that model is now, suddenly, $100 cheaper, starting at $399.
Walt MossbergJust remember: you're not a 'dummy,' no matter what those computer books claim. The real dummies are the people who-though technically expert-couldn't design hardware and software that's usable by normal consumers if their lives depended upon it.
