Projector Display for Galaxy S2

Hey, I’ve been wanting to get a display for my Galaxy S2 for a while now. I travel a lot for business and frequently use my phone as my only source of entertainment. The little 4” screen just isn’t cutting it anymore. Another major concern is portability. I need to be able to carry it in a small bag or backpack, whichever I’m carrying for the trip. I was thinking about getting one of those pico projectors I’ve been hearing about. Here’s some pics of it in action; it looks pretty good but what do you guys think?

Here's a video of what I'm thinking about:

The first is an AAXA P4-X and the second is an Optoma PK301.
