@duerig In my head I'd already spent money, so was a new shiny thing. Emily greatly relieved I didn't spend hours on restore, debug, setup, etc. Our kids have grown up with old MacBook and have sentimental attachment. Only I was sad :-).
Family 7yo MacBook died (sob). Std 13" Air is 4GB, custom order 8GB is additional $270 due to taxes, etc. (20% of Amazon's 4GB Air price!). Maybe SSD means can live with 4GB. Am I insane? @gaelicwizard
