Eh, I tried the new Maps and it seems usable. What's really wretched in this release is what they've done to the App Store. It's now HTML5-based, like the old (and despised) facebook app. It crawls compared to the old one.
Unless I'm terribly mistaken, ALL apple stores (iTunes music, iOS App, Mac App, iBooks) on all platforms (Mac, WIndows, iOS) have always been web views. Every single one of them. Ever since 2002 when iTunes was launched.
And my experience in the past few months (iPad 2, iOS 6 beta) was that the store is not slow at all, so don't worry!

The appstore has always been web-based. You could really feel it on a slow connection (e.g. Edge), because the UI itself (not just the content) would take ages to display and sometimes fail to render altogether.
