Working on it Elegran.
I don't think Desktop computers will become a thing of the past any time soon gangy5. Many still prefer them (including me). I think it's good that people have the choice between laptops, tablets, desktop and now even 'phaplets' (for those on the go). I hadn't heard of phablets either. I thought I was buying a smartphone. These now do so much more than just make phone calls that they are almost like a small tablet, hence the term 'phablet'.
. They have their place I suppose.
If you are happy using a Desktop computer, I'd say there's no reason not to get another. With some of the tablets becoming less and less expensive, many people now have a Desktop computer and a tablet ..or a Desktop computer and a laptop. All can be useful at different times.
For just the choice of one though, I'd personally go for a Desktop computer.
