I’ve wondered if the high quality of tablets (and phones) would result in a slowing of sales. People are starting to accumulate ‘spare’ deviced, which makes it difficult to justify buying a new one.
I have seen that the average iPad user upgrades on a five year cycle, compared to a two year iPhone cycle. I'm a little ahead, say three years (I skipped a couple of upgrade models) of that because I have a family I hand off perfectly good, operational iPads to when I upgrade, and I can afford to upgrade when I want to. I aim on my second year on my iPad Pro 13" and it is so far more than meeting my tablet needs. I bought it on the AT&T Next program so I could upgrade at anytime by just exchanging it for the latest and greatest, but I don't feel compelled to do so. I use it every day for several hours. . . usually reading a book or surfing Freerepublic.
