Hmm, the webair thing gives me 316.406250 GB/month
But I'm getting 459.2235 GB/month based on my calculations.
1,500,000 bits per second. Convert that to bits per month using an average of 30.4375 days/month. Then divide that by 8 to get bytes. Then divide that by 2^30 to get Gigabytes.
Either I'm screwing up somewhere in the calculations, don't know how to use the webair converstion util or it's just too late in the night for me to be doing math.
