Most of the newer plans are geared towards a lot of newer users, who generally are wanting more and more data. But understandably, there are users who still do not need a lot.
I know prior to these new plans out, there were some more basic 1-4 gig plans available.
You might want to give them a call, see if there are some still available to be added, which are just not shown on the webpage.
I went and took a look at the pay as you go section to see if there were any cheaper options there.. but your up to $65 for 1g.. at that point might as well pay the extra $10 to get the newer 10g plan.
