Speak for yourself. I have no interest in an oversized smart phone. 
You know - i was kind of like you for a while before owning a Smartphone i couldnt see the point of a tablet. But having got used to a smartphone. I recently aquired one of the firesale HP Touchpad's (Mine runs WebOS & Android (cyanogen)). I can safely say it is a handy thing to keep in the living room or to take on holiday. (Great for watching movies on a plane etc). Particularly if you are going on a budget (or so they would have you believe) airline. If you are only taking hand luggage it saves the weight and space of a Laptop. All i am saying is dont dismiss tablets completely they do have benefits over both a laptop and a smartphone.
All that said - i for one would pre-order one of these amiga netbooks provided the price is sane and the specs are good enough. For me this is the most sensible
amiga move i've come across for a while. Im sure its not going to take over the world but cost is the one thing thats keeping next gen amiga's from being in the hands of fans.
I believe that the OS is slowly becoming less relevant with the trend of moving everything into the cloud. A system just needs a good browser with up to date support for all the various standards. I've not used an next gen amiga but i assume the latest browsers on OS4 are on the ball - with the exception of Flash which thankfully is dying. I think this situation was evident to my when using the HP Touchpad's WebOS - while its App store is pretty barren - in WebOS the browser is good enough to run most of the apps in the cloud - so app support for the most part is not a real issue. Its only when it comes to games that you
find the issues. Now an AmigaOS based netbook or even a tablet wont have this problem - it already has a nice back catalogue of games which - lets face it - are the same types of games we are seeing re-hashed on the Smartphones with updated graphics.
