I like using Ubuntu (and LXDE) and Windows 7 ... there is a very nice familiarity with that user interface. But I agree that it is not so finger friendly.

The iPad2 is an atrocity considering how dumbbed down the user interface is. This is not a large phone, this is meant to be a mobile computer (think laptop) where the primary input is via finger touch.

CM7 on tablets (Nook) looks decent but really is a large phone. It doesn't make it feel like a mobile computer as I would wish.

The Honeycomb UI tries to pack more than the iPad, which I applause. But it does it in a very awkward and confusing way... it really isn't intuitive or helpful for novice users. More importantly, it isn't built for quick navigation/usage as I would have hoped.

I can't remember the Touchpad's user interface ... ... I'll try to see some videos.

SO far, the RIM Playbook has the best tablet interface because it does real multitasking and switching between running applications is a breeze. Opening new ones are relatively easy too. Its a great blend of the two.

I wonder if an Android custom rom (CM8?) can be built that implements a "app switching" just like maemo (or even like the playbook). And one that can help stack two open applications side-by-side (like the Kyocera Echo). As well as support closing apps by holding the back button (not just pausing them=wasted ram) and run apps in the background instead of just pausing them.... comon I'm not eleven, I want to be able to harness the power inside.

Even this is better than the iPad's UI: http://www.meegoexperts.com/2011/04/...-beijing-2011/
