We’ve mentioned Chrome to WP7 but the dev has an accelerator for IE8 and 9 and a bookmarklet for the other browsers, so non-Chrome users can join the party. So it’s free and only getting better.
Oh and an update is expected to bring the ability to delete links and store data offline…
installed the accelerator but don’t see a button in IE9 anywhere? how do you send it to your WP7?
