Who says they're in a rush and paying for it? I'm not sure if there's big money in pay cloud services right now, outside of the corporate market maybe. Services like iCloud are offered free of charge - value adds.
iCloud is free for 5GB, the smallest device is 16GB so if you backup to that, it pretty much takes up that space now you want to share photos between your iPhone and iPad and Mac thats more space. Documents, more space. Music, more space. Apple knows most users will run out of 5GB quickly and need more. The 'free' part of iCloud is the free hit of the bong to get you hooked.
Netbooks will be killed by Ultrabooks on the bit bigger and expensive but more usefull side and tablets on the cheaper and smaller but a touch less usefull (no keyboard less storage) side.
That said, I agree with a lot of folks here, most who own a tablet it is not all they own. Tablets are travel, reading, video watching, bit of surfing. Type a document or long email you go to your laptop, desktop, netbook or ultrabook. Could you use a bluetooth keyboard with your tablet? Sure. But now you wrestle two devices around, etc. Easy just to grab the laptop. Keyboard is already there.
I think with more emphasis on cloud OS becomes less important, and on a tablet is is least important. You dont expect a tablet to do tons of things. A laptop, netbook, desktop you expect to do more on. So in a market nowadays, Amiga OS would probably fare better on a tablet over other things. Then again, I would love to see Amiga OS on anything modern that wasnt insane priced. I bought a PowerBook to run MorphOS just to get a portable Amiga experience.
So we have to face facts, any Amiga netbook, ultrabook, laptop or desktop is likely to be sold mainly to existing Amiga fans. Tablets might have a wider audience if positioned/priced right but of course even there you have the big gorillas in the room of iPad and Android (Nexus 7 anyone?). The BB Playbook and HP Touchpad learned this the hard way.
I am glad to hear Natami is still in the works. I want to see that come out since it sounded better than most other similar hardware emulators.
