Though I've said it many times before, I'll say again, just like many of you, no physical media = I won't buy.
I've purchased a large number of $1-3 apps on my phone. If they put out awesome games that clock in under $5, then I'll consider it, but I have little interest in what amounts to leasing a game with no guarantee that I'll even be able to play it tomorrow, let alone a year from now when some server gets shut down, or an update breaks the game and the dev isn't supporting it anymore, or whatever. It's bullshit.
