Thanks for asking.
Remote Buddy's AJAX Remote is not bound to a particular device. In 
fact, it works fine on the iPod Touch, iPhone as well as desktop 
Safari (on Mac OS X and Windows).
Whether you can use AJAX Remote on a device is determined by whether 
the browser on that device
- is compliant to web standards
- supports the latest incarnation of web standards (CSS 3 is needed 
for correct rendering of some UI elements)
- runs on a device with a big enough screen to render the AJAX Remote
If I remember correctly, Nokia is using Apple's WebKit for the browser 
on their devices. So you may want to try out Remote Buddy with your 
tablet. The 30 day trial is (of course) time-limited, but not limited 
in features.
Best regards,
