Not sure how up-to-date this is, but Bing has a nice page where you can dynamically view all of the available Windows Phone 7 apps. You can filter by category and sub-category, too. (This morning, the total number of apps is over 1600.) Nice!
Thanks to thinkmobile for the tip.

I can’t get to that page, when I type “windows phone 7 apps” into bing visual search, I end up with the standard search results… What am I diong wrong?
No idea. Are you outside the US? Bing services seem to be locale-specific.
Jupp. I guess that’s it. Ironic isn’t it? If you consider that I (speaking for many Europeans) have had my HD7 for more than two weeks now…
When you are in Bing Visual search, click on the “Online Media” and then the “Applications” tab. Windows Phone 7 Applications should be listed amongst those categories.
Or, you can try this link:
Works like a charm. Thanks very much mnjoe!
Like many of the cool features in Bing, you need to set you location to US for it to work.
I like this. But it’s not great, for one thing you can’t search! Only browse by category, so I am not sure what ‘visual search’ means exactly, as it seems to indicate my eyes do the searching.
Sending a link to the phone would be majorly useful too. Zune is nice software, but I can only install it on my primary personal PC. I, like others, use many different PCs in a single day. It would be nice to be able to search for WP7 apps on the fly, on a full screen.
I’m in the US and your link worked for me. As to the comment about how up to date, I noticed there are dates underneath each icon on the “25 Newest Free” and “25 Newest paid” selections. On the sorted by drop-down option on the main apps listing, one of the choices is “Sorted by release date” and when used then all of the icons have a date underneath them.
