Reading the FAQ it doesn't seem to bad. The Indie license allows you to run it simultaneously on 2 machines and the Studio license increases that to 4. You can transfer installations to new computers (or the same computer if doing a reinstall) up to 10 times per year, so you're not locked in to those 2 specific computers for eternity. Restrictions are always annoying but I think they're striking a reasonable balance.
