Apartment with a pool in Tampere, Finland. Also I would be more likely to rent a place using a site that actually allowed me to search for apartments from a map.

Instant helpful per-minute advice from MySQL/Linux/etc. gurus 24/7 when I need it. Similarly graphic design where I could in a few moments get sketches of things and commission them to be turned into finished works. I don't enjoy hunting for talent on forums/elance and having to wait days for responses when I need something done now while I am still in the zone to work on that particular project.

Frappuccino in Finland, although I hope nobody actually does that as it would make me poor.

A mouse that makes no clicking sound. It seems to exist: http://www.engadget.com/2006/03/14/thanko-silent-mouse-kills... I'll buy one when I go to Japan next time.
