But that wait could soon be over with Microsoft CEO Steve Ballmer declaring to the crowd of his keynote at the Worldwide Partner Conference, that all of Microsoft's major partners - including Asus, Dell, Samsung, Toshiba and Sony - will be delivering Windows 7 tablets in the next few months.
"We want to give you a consumer-oriented device, but a device that fits and is manageable with today's enterprise IT solutions", Ballmer said. "They'll come with keyboards, they'll come without keyboards, they'll be dockable, there'll be many form factors, many price points, many sizes. But they will run Windows 7", he added.
Back in January Ballmer showed off a prototype HP Windows 7 tablet known simply as the "slate", but it's thought that this idea has been killed off by HP who now favour a webOS device after its takeover of Palm.
Ballmer has also promised to show off some Windows 7 tablets at the conference, so keep your eyes peeled to Pocket-lint because we'll be sure to post up anything interesting that crops up.
