well there is a G4 mini finishing on eBay tonight and i would like to buy it but doesnt have wireless which is a need for me. Is there any USB dongle's for mac that will work?

Thanks so much in UK by the way.

I was just reading around and an idea popped into my head if i bought a airport express and plugged it in a plug near the mini and used a LAN cable and plugged it in, would this connect to my netgear router and give me a internet connection?

Thanks.
