13" MBA Refurbs...Are they good or get a new 11"

Which one is cheaper? Also take note that size is a factor. For some, the 11" is the perfect size, others want a bigger size built in. Battery life is good on the 11" (about the life of the Macbooks from a couple of years ago, before they started to bump up the battery life even more with a few hardware changes). I'm a little unsure of the battery life rating on the older Macbook airs.

Then again, a lot of farmville players generally play plugged in, so I don't know if battery life is a big factor.

The 11" is definitely overkill for the simpler games. Farmville, Peggle, etc. You could crank those out with a cheap laptop running on Intel Graphics. These 11" specs are more along the lines of a good many Western/Asian MMO games (if bootcamped or running software to run PC MMOs like Crossover), and can work with lower settings of Starcraft 2 easily.

So, for her, it's easy to go with the cheapest option.

I have both the 2.13 GHz SSD rev C original MBA and the 1.6 GHz 11", and there´s not a doubt in my mind; get the 11" It is snappier in general use and it is dead quiet / cool to the touch.

The rev C 2.13 GHz is constantly running the fans and not even able to play a 720p .mkv without stuttering.

Unless you get the rev C a lot cheaper than the 11", this is really an easy choice.

I'd go with the 11". The inside improvements are pretty substantial, and the SSD on the new devices is much faster than on the refurbished old models.

yeah I would steer clear of the last gen unless you find something for less than apples refurbished prices. The new MBA has a really good graphics chip and for serious HD content you will be glad to have it.
