I like this, very much! I use an HTC 7 Mozart.
A couple of suggestions, if I may? I realise it's a test, but since
you have the domain you do...
- Add a search button for the map (perhaps between your zoom-out and
zoom-in buttons) so that it's easy to recentre the map. Not everyone
is in Pittsburgh.
- Don't add an ordinary pointer to the map if the Streetview pegman is
to go on top of it.
- Add "Forward" and "Back" buttons to Streetview so that we can
progress down a street as well as look round and zoom.
I can confirm the Google logo is entirely white in the mobile browser.
It would be really nice to be able to pan the map with a swipe.
Hopefully Microsoft will update the browser to enable the events
necessary for that.
