Quote Exalted Wombat:
Sure. But progress towards WHAT? Apple have discovered and developed a huge market for a fully inegrated iWorld with all the gadgets sharing entertainment media (with suitable DRM, of course) and a full selection of easy-use applications at the GarageBand and iMovie level. By restricting choice they can, to an extent, make it all "just work". Why waste resources elsewhere? Would you?
That's a nothing statement.
