First of all, people complaining about the 15 minute return policy, that is longer than most other app stores and at least the Android Market has a return policy. There are a number of reasons why they had to do this and was a request MADE BY the developers. This was not a Google thing. Apparently, one reason extended by developers, particularly those who do games, was that people were buying games, finishing them, and then returning them all in one day. The other reason was piracy. Either way, you could say that a few bad apples ruin the batch. In other words, there are end-users likely abusing the system that caused the change that affects the whole of the Android community. Blame them, not Google.
Secondly, as for my reaction to the Market, I think it looks better, for sure. Landscape is definitely better. UX is different and I'm sure after using it a while, it'll be like second nature. I can't say that it is better or worse, functionally than the old one. Aesthetics don't make an app better if the function is still poor. I think the security font should go back to the orange-red color than going to black because it'll stand out better. The cover-flow for the featured apps is nice, but I still think that Google needs do a better job of featuring apps. Also, where is the new categories for "Live Wallpaper" and "Widgets"? I thought that was to be a part of it, but I can't find it.
