For full-touch mobile use, capacitive touchscreens are the best solution we’ve got — and it has absolutely nothing to do with the iPhone, it has to do with the incremental improvement in usability brought about by near-100 percent touch registration. That’s a big deal, because even a 5 percent loss of registration on an on-screen QWERTY keyboard would represent roughly one letter missed every five words (assuming an average word length in the English language of just over 5 letters). Resistive screens have many, many totally valid applications, but put simply, phones aren’t one of them; they’ve been outmoded by a different technology that’s more appropriate for the size and use that the average handset sees. Registration issues aside, fingers are larger than styli, and when a resistive display is registering an unweighted pinpoint coordinate, you end up ironically losing accuracy — a benefit touted by resistive that’s really only realized if you’re using a stylus full-time. No one’s claiming that capacitive screens are the magic elixir to make human digits achieve superhuman accuracy on a tiny screen, but… you know, step one is making sure the phone knows you pressed something.
Anyhow, HTC’s now claiming that the just-announced Tattoo has gone resistive because its 2.8-inch screen is simply too small “to be accurate with” as a capacitive. The company’s tweet goes on to say that resistive “ends up registering fewer miss-clicks,” which could be argued — maybe — were users expected to use styli. Android is not and was never designed as a stylus-driven platform, and unless HTC’s driving in that dubious direction, the claim is bunk. More realistically, the resistive display is probably a cost sacrifice the company made to keep sticker shock to a minimum, which is fair enough — HTC’s trying to cover many market segments with Android, as it should — but we wish they’d been upfront about it.

Optoma’s PK102 not swank enough for you? Fret not, as AAXA Technologies is also shipping its second-generation pico projector. The stupendously simplistic P2 packs an LCoS chip, 33 lumens of output, an 800 x 600 native resolution and the ability to throw up your favorite Xbox / Atari / C64 title at up to 80-inches. There’s also a VGA output and a few on-device buttons, and if that’s exactly what you’ve been looking for, you can call one your own for $339.
