I took my SP3 out with me at lunch, I'm opening a new office and thought it would help taking notes with hunting for office space. My expectations were to have nice neat notes intermixed with pictures of offices and contact information. In practice it was a bit tougher than that. Firstly the SP3 is VERY tough to use in sunlight, it just was not very viewable even at max brightness, which of course would do wonders for the battery life. Another annoying thing was this thing is pitch black with polarized sunglasses. Polarized viewing is hit or miss, the iphone is horrible but my note 3 is ok for example. But even with the iphone I can still see the screen, but with the SP3 it literally was pitch black. The first time I turned it on at 50% brightness I h onestly thought it was bugged and would not boot up so I reset it. When it wouldn't boot up I took off my glasses and realized it was booted up, I just couldn't see the screen. Add to that how insanely glossy the screen is, bleh. On to note taking. I need a bit more practice with one note, but it seemed a bit tough to really do anything other than jot quick notes down. I think onenote needs to be revamped to cater to someone out in the field holding his SP3 while walking around and doing things. Taking pictures was tough, but that's what you get with a tablet, but inserting them in was fairly painless. The camera on the SP3 is VERY slow, as you pan around to get a shot it jitters and stutters wildly. In the end I used my note 3 camera instead and manually added the pictures. On the pen function, very accurate and nice. The pen on screen is a bit too slick though. To combat the glare and slickness I may consider a matte screen protector, even though I hate them this may be a necessity. Oh and don't get me started on oil and fingertip schmegma getting on the screen. If MS wants to position this as a note taking device then I suggest they use some R&D to invent some technology to make this more like paper in all these ways. There is room for improvement beyond cpu and other things these guys concentrate on. Contact info: I didn't see an option to add this in, it would be nice especially if this was used on a phone. Maybe have a tag that contained address, phone, notes, etc. Geolocation: This might have been nifty to have, to be able to map out the office spaces I looked at and link that to my notes, in particular the single entries and/or contact tags. Keep in mind this was with the mobile version, I haven't played much with the desktop version. I think a 8" tablet would be more conducive to taking notes in the field. The smaller/lighter form factor would make it easier to walk around and take pictures. Also I highly missed not having a pen silo, for anyone that thinks this isn't a negative I highly beg to differ. I was constantly looking for a place to put the stylus and even almost lost it a couple of times. I won't be using this for note taking in the field often so it's not a big deal, but if anyone has suggestions or thoughts on this feel free to comment.
