I'll admit upfront to being a Gagdet Guy, aka as a Toy Idiot by some who are less inclined to care about having all the latest, and sometime simply, one hit wonders. This story in the India Tech Times profiles three devices that on the surface converge functionality and make things simpler for consumers but also fit my criteria for both "casual computing" and device divergence.
In many ways the Mylo and the Nokia N810 would look to be similar. But the Linux based Nokia N810 is so much more open and powerful that you have to look really closely at the specs to see the difference. On the other hand I've yet to find a device using Skype with the audio clarity of the Sony Mylo. Sony's use of a third party codec was brilliant.
Read all three reviews and I think you'll see that consumer friendly WiFi devices are certainly getting much closer.
