Currently I am able to log in and out of gmail on a friend's laptop without any (reasonable) fear that my email will keep living on that machine (and is unencrypted). Obviously keyloggers etc could grab my password, but let's assume I'm not _that_ paranoid.
I do not have this option with the Chrome browser itself. At best, I can log into Chrome (and am encouraged to do so at first startup) and at the end of the session, I can delete the profile (rm -rf
Compare this to Chrome OS. Here the functionality is built in; you don't have to delete your user account at the end of every session. Encrypted files are stored on the local drive which you can then access the next time you log in. It's quick and painless. This needs to be built into the standard Chrome browser.
Now, related to your arbitrary and questionable definition of a monopoly, are you actually telling us that in the old days there was no alternative to Windows (*cough* *cough* Macintosh)? There was "no choice"?? And you would also like us to believe that Apple doesn't own the tablet market today? Apple prides itself on having a completely closed ecosystem. If we follow their model of "don't allow applications which duplicate functionality", then IE should still be the only browser allowed on Windows machines...
The only reason they haven't been hit for anti-competitive practices is because their marketing department, including Jobs, have always made the company seem like the scrappy outsider. Google looked that way at one point as well. Apple's time will come. It's inevitable.
