With regard to the OP's plight... how long will SL be available after Lion's release? I believe retailers have already pulled it from the shelves.
Eventually, the only recourse for non snow leopard users to upgrade would be to take your machine to an Apple Store. Ridiculous if you own a desktop. Plus, with stores few and far between it's impossible for many.
So... It's hard to believe that Apple would box themselves in like that and make things so difficult. Especially with a $30 product that is basically a loss-leader intended to sell their computers. (Unlike Microsoft).
