Well, I've had a chance to give my SP3 i7 a complete workout through my typical usage, and I can honestly say I'm torn. My typical usage is marking up PDFs several times a day, limited AutoCAD usage while travelling, general office and browsing, and notes during phone calls and meetings. So far, I've been on one day trip with a 1-hour plane ride each way, and one multi-day trip to our other office where I was working in a production environment and had 4-5 hours in the air each way. Here are some of my thoughts. Nothing I've observed is necessarily objective; I have not run benchmarks, or anything like that. I am simply sharing my observations. Also, this is before the 8/19 firmware update, so I cannot comment on that yet. Battery Life: It's been great for my needs. I watched a movie on the plane, did some light Word work, marked up a couple PDFs, and even fired up Revit for about 20 minutes and still had plenty of battery to take notes during a meeting. Basically, a day trip to NY with a 1-hour plane ride each way left me with battery to spare. Heat: It's definitely hot. And It can get hot quickly. Yesterday I turned it on after it slept for a couple hours, and a simple file transfer over wi-fi left it extremely hot to the touch with the fan (quite loud, IMO) at full blast. I get it that the form factor is small, and it has an i7, but there does not seem to be consistency with the heat and fan. It gets hot and loud even doing simple tasks. External Monitor & Scaling: This is painful. While the 150% scaling on the SP3 is great, it sucked when I connected a 22", 1080 monitor. Unless I missed something, my choice was to scale BOTH at 150%, which made the UI on the larger monitor TERRIBLE, or leave scaling at 100%, which made the SP3 virtually unusable. Neither was an acceptable option. Windows 8.1: I know I just need to get used to it (coming from Windows 7), but the dichotomy between the desktop and Modern UI is silly. I got used to the Start screen pretty quickly, but having two versions of settings, IE, etc. is just plain stupid, IMO. But I don't want to beat on that, as it is a separate conversation from the SP3, and it's been beat to death. Choppiness and Force Closures: I use Drawboard PDF for annotating PDFs, and it is fantastic when it works. But it gets really choppy and sometimes FCs. I've experienced this on other places as well. It might just be the software, and has nothing to do with the SP3 as a device. But even when doing rudimentary tasks like file management on the desktop, things just seem sluggish. And my last laptop was a Dell Inspiron circa 2006! When running smoothly, it runs AutoCAD and Revit without issue, but when it decides to slow down, it's frustrating. Maybe it's the throttling, maybe it's the wi-fi bug; I don't know. But I hope whatever it is gets fixed. Type Cover: Love it. Simple as that. I think it works great. Pen: Generally works great, but I do notice lag at times. Sometimes the lag is on the order of several seconds. All in all, I'm torn. The device is exactly what I need for my daily workflow. I feel like it's coming up a little short though, especially for a $2k device. If I had to make a decision right now, I'd keep it, but I plan to do some more heavy testing now that I've updated the firmware with the 8/19 update. I really want to love this device, but it's testing me!
