Android Market links go to 404 on non Android browsers. When will Google fix this?
It's really annoying having to check the user-agent and displaying something else for non Android browsers.
Don't use the market:// syntax anymore. You can use http://market.android.com/details?id=com.example.abc and it will be picked up by the Market app if on the phone, or if not supported (pc, no Market installed) sent to the Market website.
