Critix has been touting its "Nirvana phone" concept -- a handheld device that can be paired with a monitor / keyboard for remote desktop use -- for quite some time now. Back in February, the minimum hardware specs were nothing to challenging, and as it turns out, Apple's iPhone 4 pretty much exceeds 'em by a long shot. And it has VGA out capabilities and Bluetooth keyboard support. So, you can imagine where this is going. The company is back in what looks like the same depressing cubicle space to show off what looks to be a mature demo of the Receiver 4.0 virtual desktop client on an iDevice, pushing 1024 x 768 resolution and some gesture integration as a mouse replacement. There's definitely some noticeable lag, but hey, you gotta start somewhere. Video after the break.
