We're tending to use outs on Fridays and weekends when the house isn't so hectic with various clubs etc (Mon to Thurs). Really impressed with it.
Got a few 'proper' games (i.e. controller ones) for the kids (me) for Christmas - Fifa 2011, World Rally, another racing game but with 'power ups' so non-serious, and Sonic racing game (like Mario Kart).
Also have Halo Reach for me, and Need for Speed Hot Pursuit
We've got an older TV without HDMI, so bought the Advanced Scart cable with RGB output, and it's made the screen, especially tiny text, much more readable.
