I just happened to have glommed onto a Gmail account by virtue of knowing someone who already had one. I was surprised to see this:

"You are currently using 0 MB (0%) of your 1000 MB."

C'mon Google. You are a company chock full of computer geeks. 1 GB = 1024 MB. Yeah, a lot of average Joes in Podunk may not grok in computing things are done in base2. However, I expect better from Google.
