I'm bit surprised by all the comments about "Consistency". All of us use the web every single day and every single website looks completely different, all with their own styles, layouts, color schemes, etc. I would think that web designers, and designers in general, would be happy with the flexibility to create their own thing rather than having something that pretty much looks like everything else. The web used to h…
I see a problem with that. It's that many(most?) apps have 1 or 2 developers with hardly any design experience, and no designers. So it's important for the default look and feel to be usable and stylish which iOS and Windows Phone do. This does not mean that they all look the same, because the developers with resources can do additional design work(perhaps by hiring a designer for the next version) on top of the default UI and UX to make the apps look more beautiful and with even better UX.
Having used a tablet with Gingerbread, both the OS and the apps were pretty much terrible(in some part because the OS many apps were designed for phones and not tablets). ICS improves the design in the OS quite a bit and some apps(like the ones featured in the article) have great design, but the vast majority of the rest of the ~500K apps in the Store don't look good still, because you can't expect free or 99c apps to hire expensive designers upfront or spend too much time on design because of a very real and common scenario that it won't make any revenue worth the design cost and time. Similar apps on iOS and WP may look the same as each other, but atleast the UX and the UI look decent if you stick to the defaults.
