In case you needed more options in your choices, FYI I work on a four year old white MacBook that has been maxed out with 4GB ram and where I replaced the HD with 64GB SSD and I replaced the optical drive with a 500GB HD using Optitray.
This setup is very fast because OSX and all programs boot near instantly from the SSD, and big space eating files are stored on the HD - the best of two worlds until SSD come down in price. It is of course nowhere near as light as an MBA but for those occasions where that matters I have treated myself to an Ipad 2 paid for with the money saved on not buying an MBA which is not powerful enough for my purposes as I work a lot in Aperture with 18MP pictures. The MacBook itself is mostly docked to a Cinema Display nowadays.
If you have an hour of two and are not afraid of following the excellent guides over at iFixit.com this is all really easy and worth the effort. Backup before you do anything however!
