This is only true for your Google account, right? You're not magically logged into HN already on the new machine? Chrome isn't actually syncing your cookies, it's just that logging into the browser logs you into all your Google apps too.

Firefox syncs extensions, preferences, open tabs, etc. The only thing it can't do is automatically log into Google, but having to enter one extra username/password one time per computer seems like a pretty minor reason to pick a browser, unless you're constantly logging in on new computers.
