As long as things keep going multi-core, ARM is going to be just fine for me. x86 compatability not such a need.. We've got Linode for that. ;)
Most PC-on-Sticks' use HDMI video output. I have a small dodgy cable rig to go from HDMI out to Lapdock HDMI in, but thats just because: Motorola. It could be quite feasible that Lapdock clones will arrive soon, with standard connectors..
>I really think Lapdock+PC-On-Stick is my new direction
Ideally an ARM-based PC-On-Stick or one with a beefier Intel or AMD processor?
(I am aware that the second option cannot be powered over the USB connection.)
Also, how does the video get from the PC-On-Stick to the Lapdock's display? does it go over a USB connection and then through DisplayLink hardware?
