I was just browsing and found this. it seems very small and comes with a software cd too. Its nothing special, just the size that amazes me compared to normal USB dongles. Plus the price is very good considering it's got 802.11N technology, so very fast.
Have a browse if ur interested. i've just ordered one for my spare computer as i kept stepping on the belkin dongle. ( now even cheaper - was about 8.89 now at 8.20 approx)
