What follows is an unordered list of things I'd like to see from Apple over the next few years, starting with the easy & obvious things upfront. Most of these have Radars filed against them, but since they're more often than not dupes of existing Radars I won't post the numbers here. Most of this is about iOS, but not all - I'll say upfront that I don't think OS X has a future with the way it's going currently, and has been running on fumes for most of iOS' lifetime.
A great wishlist by Steven Troughton-Smith. Mind you, Steven is someone firmly in the camp that sees iOS as the only way forward for Apple - suffice it to say, I have my reservations about that - so it should be no surprise that many things on this list are focused on making iOS more powerful and versatile.
