...your dream device would be twice as heavy as any of the tablets today, as big (physically) as a netbook, and be twice the price of the iPad (since they have to plan on making all their profit from the original sale, not from later add-ons). Oh, and compatibility with what? There is no usable Microsoft Windows for a touch interface yet (fanbois notwithstanding); the most successful Linux-based touch system is Android, and it's got it's own compatibility problems; so that leaves the Mac. And one of the things Apple did supremely right with iOS was recognising that fingers are not mice, and designing accordingly. Don't get me wrong; I'd love to see a practical implementation of what you're lookikng for; I'd likely buy it over the iPad 9 that it would be competing against. And I do like the HP better than any of the Android tablets I've evaluated. But, really, which would you rather have: spec-based theory, or ecosystem-based practice? Those of us in the reality-based community who actually have to get stuff done will, fairly reliably, choose the latter.
