Aside from the new logo, it looks pretty much identical to how the Android Market site has looked for well over a year.

It's also logical that it would resemble the Apple/iTunes store, since they both serve pretty much the same purpose but for different platforms. Barnesandnoble.com and Amazon.com both look substantially similar for example.

It does look similar, though it does have cloud-based music syncing, more books, and other nice incremental improvements.

Could you explain more?
