By the 2010 has difficulty with a new OS version, you will be ready to drop it for a new computer anyway.
I have two 2010 MBAs and a 2011 MBP i7 quad. The MBAs are enjoyable for any task I give it for day to day use. I've used it to rip blu-rays and it plays them back without a hitch. I don't do video editing on them, however.
The 2011s are going to lose value more than the 2010s.
You are looking at probably 4-5 years before a new OS comes out that wouldn't be supported by a 2010 MBA I'm guessing
