I'd argue that modern tablets (not including my old handspring visor in this) came out when the tech was already relatively mature. I took the plunge at iPad 3 time and still use it to this day, the missus has some newer variation, but not once have I thought that it'd be worthwhile to upgrade. The tablet just still does the job.
It's not the need / want, rather that I've bought a mature product for which newer generations offer little to no benefit. Much like the TV or the dishwasher - it'll get replaced when it breaks.
Mobile phones have seemed to have a longer path to maturity, but I'd argue that they too are approaching the point of no innovation. I think we'll soon see the market there tail off as there's a united response of *meh* to the new offerings. Although, the 12-24 month contract/'free' upgrade cycle may prop them up for a little while longer.
