I've refrained from sharing my impressions since I work for Microsoft, but after owning my SP3 for a few months now (personal device purchased with my own money at full price!) here's my summary:
- The "lappability" complaints are pretty much bull unless you're a super tiny person. I use mine on my lap *all the time* and I'm short/average height, around 5'7". I've written specs and worked in Excel for hours with the device on my lap, and it rarely if ever falls short compared to my Dell XPS 12.
- In many ways, it's better on my lap than a laptop because the heat is in the screen rather than the base
- I can also prop it up on my knees like this image I previously took, something I can't do with a regular laptop:
- It's super fast, and I love the 3:2 screen. Every time I use a 16:9 laptop now everything feels unnaturally squished
- Battery life is good, but not great. Maybe it's because Outlook 2013 is a battery hog and I have that open all the time. I get around 5 hours, which is much better than my XPS 12, but not quite what I was hoping for. Sometimes drops to 3-4 hours if I'm doing heavy web browsing in Chrome
- It's fast enough to play the types of games I want to play on here - Puzzle games, 2D indie games, simple 3D games, and the type cover lets me play most of them without a mouse
- The DPI of the screen just makes it gorgeous
- The kickstand is wonderful
- The Type Cover works really well, but still feels a bit mushy. I can still type on it for hours, but I hope the next one has more travel and stiffer keys. Better than the Type Cover 1 or 2, for sure
- Even after this week's firmware update, I still have wi-fi issues. I'll resume from connected standby or hibernate, and occasionally have limited wi-fi until I reboot it. Better than it used to be, but still a problem
- The trackpad is the best Windows trackpad I've ever used. But unfortunately, that's only true for native Microsoft stuff - the Start Screen, Internet Explorer, and some others. On the other hand, applications with custom UI like Office 2013 and most 3rd-party stuff like Chrome still have sluggish two-finger scrolling. The good stuff is as good as a Macbook, the bad stuff is better than all other Windows machines, but still bad.
- The weight and thickness are just marvels of engineering. I cannot comprehend how they fit everything in there. I have no need for it to be lighter or thinner at this point, it's the most portable computer I've ever used.
- One final minor point: I love the USB charger on the A/C adapter. Such a smart little feature.
Let me know if you have any questions, though that this point I'm sure you've already found your answers
Yes yes yes and yes. But I'm having really good battery life, even when using Visual Studio, which is very nice.
Also, I kinda like the mushy keyboard... It allows for the screen to be still on your lap, while the keyboard is the one that bends a little. In a regular laptop the whole unit, including the screen would wobble a little too, which bothers me more.
I went through a 13 hour flight with mine, it wasn't even fully charged up (about 75%) and I managed to do some coding almost the entire flight (of course, I took pauses to eat and take some naps), but it definitely lasted at least more 6 hours.
Btw, this also works great on the little desks on the plane (I forgot how they are called XD), I had more issue with my mouse, since it was an uneven surface than with my surface
Oh, and Visual Studio is fantastic on this screen too! On he surface 1 it would get too cramped and you'd get to get everything too small to fit. On the Surface 3, by default it almost feels like there's too much space left, all my docked stuff is bigger than ever, even compared to when I use on my laptop with an external monitor.
I also love the new charger, how it's thinner and lighter, have longer cords and the new connector is much improved too.
My only complain so far is the pen slot on the keyboard... It sucks that it's an adhesive rather than built in to the cover, and also it's really hard to get the pen in there. Though that is a much better solution than on Surface 1/2.
