Notes: I don't have a laptop, because I'm too cheap to buy one I want, but any that I can afford I don't want. I also don't have a big screen, nice smartphone. Having either of these might make a tablet much less desirable or used, for me.
I used to listen to this podcast. One of the hosts railed against tablets when they were brand new. Saying how stupid they were. One day, his girlfriend bought an iPad, and he fell in love with it. Wouldn't stop talking about how great of a niche, but useful and fun device it was. That occurrence has been implanted in the back of my mind ever since.
I've never thought I'd actually use a tablet. They seemed mostly pointless, but then I would always remember the above. The thought gnawed away until I finally relented. I decided to get a Nook HD+. Try not to laugh, but at the time it was the best value tablet around. $150 was fairly low risk for trying out a tablet, and it had a nice screen and specs for the price. I now use it almost every day.
It's a good thing I bought a casual tablet, because that's the only purpose I use it for. It's great for looking up something on Google that pops into my head in the middle of the night. Good for paying my credit cards off while traveling. I should reiterate that I don't have a laptop. Most of the time I casually browse internet forums, or read books on it. It's also easily useable while on the toilet. Not essential by any means, but I'm surprised by how much I use the thing. Because it's so small, light and portable, it's really great for consulting DIY guides and videos on it while I perform the task right beside it.
If I had less sense and more money, I'd buy a fully loaded Surface. That thing is sexy, but way too expensive. It also needs a slot to hold the touch pen. Maybe Surface 3 will fix that, and I'll move on from the world of tablets and live in the glorious hybrid future? (I have a powerful desktop for real play, and work) Ideal setup: powerful desktop for work and play, Surface 3 for laptop and tablet purposes and an e-ink e-reader for books (or just a real book).
