One trend I am really noticing this year is the number of small ION based PC’s which you can mount on the back of your TV using the VESA mounts.
I was standing by the Microsoft stand earlier and someone asked about a large screen-size all-in-one pc and I got to thinking why would you choose an all in one when you could have a Set Back PC on your TV
You could couple this with either an air-mouse style keyboard, or indeed the multi-touch remote Ian mentions on the CES coverage on the podcast, for control. You would then have a very impressive all-in-one equivalent for a few hundred dollars.
In fact people would never know you had a pc unless you told them – they would just think you had a very intelligent TV.
