I think Meego is going to do well. There is no question.
1. It is the right direction - mobile computing
2. It is new. It is the opposite of symbian. It is for the future hardware and integration of the hardware.
3. It is built for touch. We all know the story about symbian, and the experience between E71 and N97. It is hard to convert a non touch OS to a touch OS. Symbian is probably the best OS, but worse for touch screen.
4. Maemo/Meego is actually liked by Eldar. This means everyone has a chance to like it, even non Nokia supporters. I think it is hard to have iphone people to like a Nokia OS. This is very important and it is the proof that meego has something different yet also something better.

The current UI is bad, especially when comparing to Windows Phone 7 software, simply heaven and hell. However, it is the right direction, and it is still better than the first iOS. The right direction is above everything.

Eldar also said that the actual Nokia version of Meego is better than the tablet version. For me, Maemo 5 is not there yet, but so very close to the best mobile OS. All nokia needs to do is make a more complete version of Maemo into Meego, together with Qt, it will be the best. Let's wait and see.
