I love the dell venue 8 pro (5000), but I really wish dell would stop fucking around and go all out with it. Give us a proper display output, let us charge and dock at the same time, give us a 4GB option, get USB 3.1 with type-C connector on it, put some properly fast storage on it, give us the beautiful OLED 'infinity' display that you're offering on your android tablet for the windows version too. THAT would be a device worth raving about. The CPU, the battery life, all the technology is there.
Instead what Dell do is release a 3000 model, with no digitizer and 1GB of ram. I have to assume that Dell are far too afraid of cannibalising their mid-range laptops to produce something truly great in the small tablet space, a very foolish and short-sighted position I think.
I don't think you get to trumpet 'fits in your pocket' if it's 8 inches. I don't doubt that in principle, you could persuade one to fit in your pocket (unless you're female) but I don't think it fits most peoples definitions of that.
Sorry to disappoint you, but it absolutely does fit in my pants pockets and all of my jackets pockets.
UPDATE: Here's an image gallery that I just made showing it in the jacket I'm wearing today, in the pants I'm wearing today and again in a pair of pants that I grabbed out my laundry pile - http://imgur.com/a/hFeDo
Not only does it fit in my pockets, but there's room to spare. Maybe it won't fit in some skinny jeans, but I don't wear tight pants because I'd rather be comfortable. In any case, whether it fits in your pocket or not isn't the point - it is true that Apple doesn't offer a highly portable device that runs a full OS for over 10 hours
