Hospice, - have you done or seen someone do graphic design or CAD like 3D modelling on a tab and render it? i really would like to see...i haven't seen a tab with a sufficient processor for that rendering leave alone ease of use. But it would be great relief if there is.
" i've come to realize it is not that comfortable to work from when doing serious work."
It depends on the kind of "serious" work you want to do. I think you can do good editing work with a tablet nowadays, when you really get used to it. I've learn't to do great things with my iPad - it is just a matter of training and patience.
Tablets will certainly become the primary computing devices for most people in a near future. Advertizers may find it easier to track users as they will stick to just one environment - which will likely be the mobile environment.
Identifying users as they cross channels is critical to our analysis in the future so many companies still can't determine what type of device a user is coming from much less if the same user as a multi device user. This solution sounds like it will bring great insight to organizations.
I carry my tablet with me just about everywhere with me, I also toss a bluetooth keyboard in my bag and bring that with me as well. Though I enjoy using my tablet for a lot of work functions, I still mostly use my phone when I am in a pinch. It is really my go to device at this point.
The abundance of apps is staggering and makes me wonder if developers are getting conned in some ways to bring more and more to the market. In encouraging the invention of more and more at small cost, the "higher" in the food chain can benefit.
It will be interesting to see data for use by varioius devices to get a better idea of the usefullness or not of new apps.
