Roku vs Roku 2? Should I upgrade?

So here's the story.  I have the latest hardware for the original Roku.  I bought it last year around christmas, and it works amazing.  I'm just kind of wondering if I should just take the plunge and upgrade to the Roku 2 now instead of later.  The games thing is cool and the motion controlled remote is intriguing.  Anyway, besides the there anything really that the Roku 2 can offer me that my current Roku can't? What do you guys think?
