I used to feel the same way...until I got a tablet. I still use my desktop most of all (sheer power, multiple monitors, and my mechanical keyboard). I use my laptops mostly to connect to my desktop remotely (which is quite a bit actually). The tablet is used exclusively for content consumption. When I have a question and I want a quick answer from the internet? Tablet. When I want to search recipes for what to make for dinner? Tablet. When I am planning my next vacation while sitting on the couch? Tablet. I could use my phone for these things, but it isn't more convenient than the tablet and the large, clear screen makes the experience more enjoyable and useful (Nexus and iPad here). We now have three tablets in different form factors and all of them get significant usage. The phone is great for on the road, but if given a choice, I will almost always reach for the tablet.
As for windows8 and making software for tablets, I haven't run into this yet, but then again, I don't use Windows and the only Apple products I have run a mobile operating system.
