Special Google Search for Nokia

Google today announced a special add-on for some Nokia phones:
[I]f you have an N-series or an E-series Nokia phone you can download a small search shortcut directly to your phone’s homescreen. Once that shortcut is in place, you’ll be able to bring up a Google search box (without opening your browser), type in a query and get straight to the results.
Anyone with a Nokia smartphone who wants to give this a try (you can download it at mobile.google.com) and let us know if it works well?
