For a brief moment a couple of weeks ago I considered buying a new laptop so that I could work anywhere. My choices were wither an Ultrabook or a MacBook Air. I weighed up the options and considered the pricing and ended up spending £39.99.
Yes, I did not buy a laptop of course and instead chose a hardware keyboard for my tablet. You see, my needs when mobile are limited to writing, research and more writing. When I have a project to complete, I no longer expect to complete 100% of the task on my tablet. Images can be captured and converted on my desktop and so will the finished project be uploaded, spell checked and analysed for completeness. Some things are best done on a desktop and the majority of the tasks I would have previously used a laptop for can now be undertaken on a laptop.
Those tasks include email, web, writing and a few other things. Tasks that the vast majority of normal people use a laptop for. When I consider what I would use a laptop for and the fact that the desktop would still be used for many tasks even if I owned a laptop, a tablet still does all of that and with the benefit of longer battery life and extra portability. Plus instant-on, cheaper apps and so on and on.
I don’t need a laptop anymore and cannot see a time in the future where one would fit in between my desktop and tablet.
