> I haven't updated to iOS6. I was worried that google maps would be deleted from my iPad and replaced with apple maps. I do not want this.
I'm also waiting for 6.1 at least to see how Apple Maps will evolve, I have no sense of direction whatsoever so I need maps to show me where I am, and Apple Maps still seems a bit too risky for now. It's possible to use the Google Maps site directly, but in my tests it's less responsive and the geolocation doesn't work as well as in the application itself.
> I heard somethings about Safari being buggy.. I didn't really want this either as I only really use my iPad to surf the web.
I've seen developer reports, but no reports of user issues. Quite the opposite, webkit's been updated in iOS6 so Safari is apparently significantly faster.
> I was concerned about the memory footprint. As I understand it app's now download retina resources whether you have a retina iPad or not.
It's always done that (ever since the release of the original iPad and the creation of "hybrid" iPhone/iPad applications), the version of iOS you're running is completely irrelevant to that issue: if you're running an application compatible with all iOS devices (3GS to iPad 3 at native resolutions) it may very well bundle 4 different copies of bitmapped assets (or even 5 for e.g. startup screens, since the iPhone 5 has a different resolution than the 4/4S). I don't believe iOS AppStore bundles have every been stripped. I'm not even sure they could be since they're signed (unless you jailbreak).
