Before this discussion continues, I want to point out that I'm not here to sell anyone on the touchscreen or the tablet computer. I hold my hand up and freely admit I'm not about to give up my keyboard and mouse any time soon.
In the world of the tablet I was quite late to the party, I liked the iPad but it was too big for my needs... It was the iPad Mini that got me interested... Now I have found I can design websites, write computer programs, make music, build PowerPoint/Keynote presentations and even work on my spreadsheets with ease on my little iPad mini... It has cellular data, so it's always on, all my data is with me when I want it.
It was cheaper than a laptop, it's lighter an thinner than a laptop, the battery life is matched only by a MacBook Air... I really like this new form factor, it changes the way I can work in mobile situations.
If you don't have such a mobile lifestyle, I can understand why you aren't so interested... But for me, this is now an integral part of my life.
