Salesforce.com — no software?

Am I the only one that finds it ironic that, on the one hand, Salesforce.com’s marketing rallies against installed software (examples: their toll-free number is 1-800-NO-SOFTWARE, the banner on their frontpage has a big “NO SOFTWARE” image in it) but on the other hand, the only way to realistically use the Salesforce.com service on a mobile device is through a piece of… installed software?

Hey Salesforce, Marc Benioff — where’s the skinny/thin client? Everyone else has one.
