Can a tablet computer be a low-cost alternative to home care? (US)

Frankly, Editor Steve gritted his teeth when he saw ‘Low-cost alternative to home care’ as the tagline on the Memo (Memo Touch?) website (http://memotouch.com/) and Gizmag didn’t think much of it either, but for more techie reasons. Read the comments too. But the basic concept is surely sign of things to come. [Compare with Mindings which got a mixed reception from Telecare Aware readers.]
