Today I've open IE and I've found
this [fotos.eresmas.com]. It's a button to activate Google Compute that takes you to [url:http://toolbar.google.com/dc/aboutdc.html]this page[/url]. If you decide to turn Google Compute on or remove it from your toolbar it appears no more. If you select the option "Not now. Maybe later" it takes you to [url:http://toolbar.google.com/dc/trylater.html]this page[/url]
It seems that Google has decided to make the Google Compute available.
