I've switched from vanilla google.com/co.uk to using A9.com. It's really nice and does a lot more than google. Fine for while I'm at work (with bandwidth to spare). At home, all those images would take an age. Although, I could use it to centralise my bookmarks. Hmmm. Hopefully, they'll let you switch to international versions of amazon at some point.
Also loving the search bar in Firefox - with the various plugins you can download. Clever.
