Thanks for fixing this!
I see on our pricing page that the base config for shared-cpu-2x is 2 shared CPU/512 MB, do we want to list that instead, or is the higher 2GB memory a more real-world example?

@kcmartin hmm good question, usually I expect one to go from shared-cpu-1x@256 to shared-cpu-1x@1024 so I dont have opinions, but Im up for 512MB wdyt?

How about the next step up on the pricing chart, 1 GB memory? @lubien

@kcmartin done!
