I don't get this. How do you think iPod isn't designed for a tablet? Is it just the unlock/homescreen that irritates you?
Actually no. Since I use a smart cover, I rarely ever see the unlock screen. It really just stems from the organization of iOS. iOS works fine on the iphone/ipod, as it was originally designed for the smaller screens. But I don't know about you, but I feel like a hell of a lot of screen space is wasted on the ipad by generously spacing out apps. I'm not saying we need more apps on the screen, but useful realtime info would be nice.
Not only that, the general organization of apps is atrocious. Why should all my games be clumped together with all my other apps? Of course the answer here, is to reorganize, put all games on a page and in folders categorizing them by genre. But here's where I'm going to ask a stupid question. Why doesn't iOS already do that for me? The app store is already laid out by type of app (games, productivity, video/photography, etc) and even by genre of games (platforming, puzzle, board, action, sports, etc). So why are all my apps thrown by default on this blank board for me to reorganize? For a company that is known for making good human UIs, it just seems backward.
And perhaps a lot of what I'm saying might be how android does it. I dunno, I can't say as I've only used android in the little time I installed it on a touchpad. I just know that apple could do a lot more to make the ipad's OS properly use a large screen.
