Hiyya Croc no mate I think it depends more on the broadband you have I have Telstra ADSL+2 at home it can be reasonably slow the Telstra Elite wireless is not bad I find away from home on the laptop but it certainly isn't instant.
If yu get the wireless for a laptop get $150 deal as the 1 3 6 month ones are crap the $150 lasts a year and I think about 10GB download. Enough for what I want it for anyway.
Depends aloy on where you are bush or otherwise.
Hot up there?? is roasting down here
