All platforms with Adobe AIR: Free desktop application GMDesk provides quick access to Google services in a standalone window separate from your browser. GMDesk separates Gmail, Google Reader, Google Calendar, Google Docs, and Google Maps from the rest of your web browsing, and provides keyboard shortcuts to switch between them (Ctrl+ or Cmd+1 through 6). You can't install browser add-ons like Better Gmail or Better GReader in GMDesk, and currently it displays too-small text in Gmail (though the developer is working on a fix for that). Ultimately GMDesk doesn't offer many features that make it worth using (or much better than apps like Prism or Fluid), but it raises the question: If Google released native desktop apps like Picasa for Gmail, Google Calendar, Google Reader, and Google Docs, would you use them? Until they do (which may be never), GMDesk is a free download and requires Adobe AIR to run.
