There's a key on the keyboard labeled either RETURN or ENTER. When you use it it breaks up your typing into things called paragraphs. When your typing has paragraphs, it makes it much easier for others to read instead of being a giant block of text. Without them, it's hard to tell where one thought / idea ends and the next begins. Try it sometime, you might be surprised at how well it works.
Poor sentence structure not withstanding, the world is moving towards a post desktop/laptop era. MS is very late to the game, and they have some huge ground to make up in the mobile market. Here, I'm referring to mobile as both the phone and tablet space. Android activations are north of 1 Million units/day. Apple has quite a bit daily as well although I can't cite you statistics. Has WP8 even activated its first million handsets? If WP8 can't keep up with the sales of the competition, let alone surpass it, MS can't make market share gains on the leaders. It's fairly simple mathematics to see that. The best they can hope for is to mop up with what's left. If 7 out of 8 smartphones sold run Android + iOS (and that's the current share) that leaves 1/8 for MS at best.
They are late to the game with their product so they have a very difficult time in the mobile space. They are haunted by their earlier failures and the brand image is tarnished. Steve Ballmer isn't Bill Gates, and he doesn't have the same gravitas either. For that matter, neither does Tim Cook compared to Steve Jobs. That it took years to come up with Windows 8 after the perceived failure of Vista and the modest success of Windows 7 (basically Vista polished up) means that they've become slow and cumbersome. This is the path to diminished relevancy.
In the mobile space, they basically cut off the WP7 adopters from an upgrade path. This is bad PR that they sincerely can't afford.
By comparison the competition (Apple and Android) have pushed multiple major versions of their mobile OSes.
The numbers are what they are, but feel free to argue the math if you'd like. Feel free to say that I eat too much Gingerbread.
