Hi Patsy -- did you mean Gamespot or Gamestop?
I've also had a good experience with GOG and would recommend them.
I recently bought the Cyan package from Steam and have been playing Myst Masterpiece Edition on my Win 7 64-bit computer in Compatibility Mode. The game plays okay -- the "flyover" videos while linking are apparently disabled, though, and it does crash every time I exit the game.
You may not experience these problems on your laptop, but I thought I'd give a word of warning.
