Hardware, Embedded Systems Okay, I think we can all agree on the fact that while Microsoft's Surface machines might not be particularly useful for most of us, we all secretly want one, or something similar. Thanks to EXOPC, you'll now be able to: for $1299, you'll have a 40" multitouch interactive desk.

Graphics tablet

Well, the reason I'd buy a graphics tablet anyway is input precision.

The core problem of every finger-based touchscreen since their introduction is that they have a ridiculously large pointer, do not allow you to see what you're doing, and give zero "hover" haptic feedback. In short, they only work if you're using software with gigantic-sized controls, and even then it's a waste of screen estate and hand movements.

To the contrary, like a real-world pen, a graphics tablet allows you to point and draw things with an absurdly large input resolution that only leaves your screen as a limitation to how precise you can get. You can draw whatever you want with slight movements of the wrist.

For serious graphics work, except as a voluntary artistic challenge ("say, how far can I get with nothing but an iPad ?"), finger-based touchscreens are probably an unnecessary hurdle.

A few notes, and I reply here, because of the precision issue.

1.) AG Neovo already offer two large multitouch screens, the TX-W32 and TX-W42, at halfway reasonable prices (below 2 grand). These of course seem to have the mentioned low precision.

In many applications, eg where a large panel with very dynamic indicators and lots of controls is required, this still should do very well. Think FOH consoles and effects (one flightcase fits all), or industrial plant process control.

2.) The Samsung SUR40 mentioned has pretty badass technology driven by Microsoft. Their hardware division is good. This uses a checkerboard pattern of backlight and IR LEDs. IR is reflected of whatever is in front of the screen and scanned PER PIXEL (!). It is effectively a bastard child of a TFT LCD and a CMOS (likely, or CCD) image sensor.

Given that they have to ramp up a mostly new process in a TFT fab, I would guess the device is a loss leader and Microsoft pays Samsung a good amount of cash to stake the claims in surface territory. The price is low enough to be very affordable to serious product developers (those who ship boxes and answer a helpline), yet slightly too painful for the buy-whatever-is-new crowd.

3.) The ExoPC-Link in the article leads to just a few tablets. The _ExoDesk_ can be found on the web however.

At the price point I wouldn't bet against that the ExoDesk somehow (though it's 40 vs 32/42 inch) is the AG Neovo technology with a simple PC board slapped to its back.
