I find it interesting that people are complaining both about the lack of a web app and about Google keeping message history on their servers. I'm assuming they will eventually build a web app, but you can't build a useful one unless you have the message history on the server, encrypted in such a way that the web server can decrypt it and serve it to the browser.
Unfortunately, you really do have to choose between privacy and having a web app. I'm not sure which I value more, TBH.
