Interesting. How many of Google services are paid so far? I remember the old Blogger had a premium option, there's Google Answers, and there's hardware like Google Mini, but otherwise I don't think Google goes this way often. Maybe they want to appeal to those company decision makers who think if it's free it can't be good :)

Philipp: as premium is a mainly meant as a support (or SLA) offer, it makes sense imo. It's difficult to advertise in a support call ;-).

An other service that is premium, extra Gigs for Google Photo...

Just as having a budget line for every expense is important, things like uptime are huge as well. Companies are looking for reliablity. With a free service, Google can just inform the customer that, owell, it down until we fix it; when you have a contract you can add an uptime clause, which is the dpendability a large organization requires. The old adage "time==money" comes to mind...
