i echo the congrats and everything else icey says, basically.<p>things that i would add:<p>- consider just sitting on (some/most of) the money for a while.  you don't need to make a big hasty plan and execute just because you have some cash to spend right now.  thats not to say do nothing.  just don't throw all your resources at something immediately just because you have the resources to burn.<p>- diversify.  as you said, the app store won't be forever.  try looking into other things that are either just becoming viable for development, or things that are going to be longer-lasting.<p>- pad your account.  no matter what you do, there will be dry times and hard times.  make sure you're good to go for that.  stash some money away while you have it.
