This is a good question to ask as far as data plans. ATT has the media net unlimited plan for $15/month that I use on my Nokia E71 and N95-4. Win/Mo phones and Blackberry phones and iPhone (or anything with a qwerty that they sell that they consider a PDA) are charged $30/month for unlimited data. These plans are coupled with voice plans. If you look at their web site they only only truly have ONE plan that doesn't include voice and that's the DataConnect plan designed for laptop HSDPA cards and they charge $60/month for that. I would love to see a $15 or $20 plan but it may be that the only way to add cheap data is to add a line to a family plan for $9.99 and add the $15 media net plan to it for a total of $25 plus taxes. But by the time the "N900" is released ATT may have changed their plan pricing so we'll have to wait and see.
