Honestly your comment would be valid if you'd actually used one, I think.
I'm definitely NOT a Microsoft shill; I have a Macbook Pro I still use for photo editing that I do rather like even if the lead-free solder on the GPU is a problem (I plan to fix soon). But anyway, for years I've avoided most Microsoft products; I have had several Android tablets, my MBP is my fourth, I've had Macs since the 604 days (and had an original Mac before that)... I've put Linux on dozens of laptops and still manage Linux boxes at work as well as storage and Windows servers. I tell you this because I want you to understand where I come from with my next statements:
I got a Surface Pro... first gen, 128GB storage, 4GB RAM. I have the Type Keyboard 2 attached to it. And you know what? When I leave the house it's the computer I take with me most often. It's small enough that I can carry it anywhere, and resilient enough that I don't worry about throwing it in the pannier of my motorbike. It'll survive... damn thing's built like a tank. Most times if I'm at a coffee shop, I'll be reclining with the keyboard folded up the back... or just detached and left in my car or bike. This little laptop/tablet hybrid has become my go-to device every single day.
Is it as good at photo editing as my MBP? No... the screen's not set up for that and the storage is WAY too small to manage my significant library of 12MP RAW pictures from my Nikon. But you know what? When I did a wedding shoot a couple of weeks back I was able to pull the Micro SD card out of my camera (it's in an SD adapter for my camera, but I digress), I was able to slip it into the MicroSD slot on my SP and then the happy couple were able to swipe through the raw, unedited shots from the wedding before they'd even finished their first drink. Then I was able to download the pics to the local storage, clean off the card and repeat the whole process at the reception. When I got home two days later I moved the pics to my MBP for editing. No muss, no fuss.
Is it a games machine? No... but no laptop is. I have a dedicated machine for that.
But damned if it hasn't become the most useful laptop I have. It's supplanted an iPad and a Nexus 7 in terms of tablet functionality because it can do everything they can. It's supplanted most of what my MBP used to do (you know, being portable...) because it does ALMOST everything that thing does. The high-end stuff I need to do (photo editing is resource heavy) just isn't great on the SP, but it doesn't have to be. Chances are my gaming rig will get some new hard drives and start serving duty as my Photoshop machine, too and the MBP will go up on eBay.
That's the thing though; the SP might not be what you need and might not fill a niche in your life. That's cool, but personally I've found my SP to fill niches I didn't think of when I first got it. I take notes during meetings using the stylus (which by the way is freaking awesome!) and I find myself whipping out my SP at work and propping it up on my desk as a third "reference material monitor" or even a photo frame if I feel like it. It's amazingly adaptable because it's a computer. The fact that it runs Windows is actually irrelevant to me any more. There's very little that can be done on OSX or Linux that can't be done on Windows. Hell, if I want to run X applications from my Linux servers I can fire up MobaXTerm, SSH in and launch whatever I want and have it seamlessly on my desktop. You know, just like I used to do with OSX. It's also no more locked down and limited than OSX, and it might even become the more open of the "big two" commercial OS's the way Apple is going. So what do I lose?
And there's the rub. For people who are really OS-agnostic in what they do (which should be everyone in 2014... seriously), the SP is a great laptop and a great tablet. It's heavy, yes... that's probably the worst thing I can say about it, but it's seriously no heavier than the first gen iPad that I still have gathering dust somewhere. At least it feels that way when I hold both of them. And it might just push me back to Microsoft full-time as Windows for all its warts is still a better gaming OS than OSX or Linux. They've come a long way, but SOOO many games are still Windows only. Since Photoshop is literally all I have left that requires my MBP and by extension OSX any more, what's compelling me to stay with the Apple ecosystem? Nothing. Photoshop runs just as well on Windows, if not better... and I get the advantage of leveraging the GPU for something that makes me a bit of money (photography) so I can then start to prop up my gaming with that.
And Windows 8? Really... you have to try it on a device that it actually makes sense on. While I don't like Metro foisted upon me, either I do find that it works fantastically in "Tablet Mode"... i.e. you have no keyboard and want to relax on the couch and surf the Internet / watch a movie. In some ways I find it a better "two-thumbed OS" than iOS on the iPad. And the desktop... well, just install Classic Shell and you get your Start Menu back for when you want to use it as a desktop machine. I do... I use it both ways and love having that flexibility. On a machine that isn't dual purpose, the dual UI makes no sense and I still think Microsoft's retarded for foisting it upon users who have no use for it... but again, with Classic Shell on my work laptop (that also runs Win 8.1) I haven't seen Metro in months. It boots to the desktop and then I work.
TL;DR: Ex Mac addict, ex Linux evangelist, current Surface Pro user finds it actually delivers on the promises Microsoft makes. Probably going to replace his Macbook Pro with a Windows PC on the strength of that alone. And OP's TL;DR is full of false dichotomies that do not relate to the subject at hand.
