I expect there'll be options for this, but I also expect they won't become very popular for a number of reasons. The biggest that springs to mind is that this puts a lot more strain on the battery of the phone, the device that you most want to stay charged. No doubt this will be mitigated by lower-power electronics and better battery technology, but I think we're still many years from people having tons of battery capacity to spare on their phones. Anyway, I hope systems like this will be built, in part because I like to see all the evolutionary options explored! But I don't see anything functionality-wise that appeals to me personally from systems like the Atrix, while the disadvantages seems pretty clear. EDIT: I should say that there is one clear benefit of an "all-in-one" system: having all your data with you all the time. But cloud-storage with automatic push of documents and media allows a similar benefit.
