It's from Wyse, so it's basically a "thin client". Don't get me wrong, Wyse makes good thin clients, but it's not fundamentally different than anything out there already. It's basically a way to run "VDI" (Virtual Desktop Interface) from your pocket.
OK, cool enough, but I can already do that with an app on my smart phone. I can run a plethora of thin client software - Citrix, VMware, Webex, PCAnywhere, Microsoft RDP, VNC... what else? The only unique thing I see here is that you can attach to a larger external screen. With an iPhone you can do that via an Apple TV with mirroring. The experience isn't fantastic but it's only a matter of time for that architecture to improve (same with Android equivalents).
I do not see myself carrying yet another device. I could see myself using my phone this way if the external graphics worked better - and there is nothing technically stopping that from happening now.
Apple or Google/Android could blink and destroy the market for this device.
