Data Usage up almost 10 fold!!!!!!

I've noticed a significant increase in my data usage too.

Storm 1 (300-400 Meg)
iPhone 1 gig
Droid 2.5 gig last month and half way into this month I'm just under a gig

Most of my data is streaming audio (slacker). I dropped XM for that reason.
 
I'm 8 days into my billing cycle and have used 251,839.24KB on my Eris. This weekend I'll be going from NYC to Washington DC on Amtrak. I'll probably be streaming music or watching YouTube nearly the whole way down. Now I am curious to see how much data I'll use.

With my Storm I usually used 250-500 MB a month.
 
Last month I used approx 4.5gb out of my 5 "unlimited" gigabytes. Hah.
 
I think that part of this is the "ooh-shiny-new-toy" phase. My usage for December was 2.4GB. My cycle is almost over and I've only used ~500MB. But yeah, still more than my Tour..I couldn't get past 50MB on that thing. Then again, it wasn't much fun..
