What sort of speeds you getting? I did have a "85Mbps" link between a room in the house and the garage but the throughput was awful. I assume because it had to actually travel all the way to the breaker panel and then back out again as they were on different circuits.

I can't really think of anything in particular that would be a secondary gadget though that I bought in 2010.

The Mikrotik 450G router I got for my FTTC line has been working great and much better than the Cisco 1841 I was using before. The 1841 costs several times more than the Mikrotik but only has a rated throughput of around 4Mbps with features enabled.

The Apple Magic Trackpad I got as a late Christmas present but was technically bought last year I've found to work very well. Not sure I'd blow £60 on it myself since its a bit expensive but if you do like multitouch trackpads then you'll like the Magic Trackpad.
