^^^heh heh, ol' Bess is no Ferrari that's for sure (though once I drove it at its top speed to check if the number on the speedometer was there for decorative purposes or not). Even in brand new condition it would not be something a valet would offer to park at any chi-chi Silly-con valley gathering.
Anujan-ullah, convergence != shoehorning same UI across device categories and trying to make one behave like the other. That is a common mistake people make. Convergence can happen at multiple levels. It can be at the HW level, system level, UX level, content/storage level etc. At the HW level I would argue we are already seeing that happen. At system level, Android (not necessarily talking about Chacha here) and Mickey have that, FruitCo to a smaller extent. We already have good convergence at content/storage level in its basic form with SkyDrive/GoogleDrive/Box/Dropbox though certainly lot of scope for improvement. At the UX level convergence means that the same 'user experience' transfers between device categories - that is different from the same UI being shared across device categories. You don't want your game console to behave like your desktop or your tablet to behave like your desktop either. But when switching between devices, if a user knows how to do X in one device category, he should not have to think or learn how to do X in another device category - the experience must feel natural (and at its best, not require conditioning). That is convergence. From a UI perspective, there is commonality in look-and-feel when it comes to design language, fonts ityadi but that doesn't mean you shove the same UI in and hope for the best. Fruit Co.'s iPhone and iPad are converged devices but when Android tried to do the same, they essentially fell flat on their face. The reason is this is not a data driven/formula driven design. A lot of factors which are not measurable go into this hence, the only option is to iterate and test till the design converges (convergence of convergence!) and if solved there are some very real tangible benefits from it but it is a hard problem. To begin with your core design language has to be constructed in such a way that it is amenable for convergence (like Fruit Co. did and Mickey is trying). And it is inevitable to see the iterations in between have schizophrenic qualities or in words of DSP Bhurelal in Gangaajal: "Yeh to saala hona hi tha".

One way to force convergence is to force adoption of certain UI modalities across devices (touch, speech). This is probably what Mickey is trying to do by forcing laptops to upgrade into touch-and-type versions.
