I installed and use the Urban Gear Case. I love it, as im out in the field and it adds some heaft, extra grip, and sense of security. Now the case does add almost the same weight and size of a naked SP#, it feels like im holding a 12" SP1. The case has a kickstand with 5 angles, and I use at home/work/school and in every aspect of what I did before adding this case I haven't come across an angle/problem yet.
Now I would only recommend getting this big/bad case, if you need it. It adds weight and thickness. I have it, love it, but I feel I need it. As a electro mechanical engineer I use it on the production floor a lot when working with customers troubleshooting problems, and the added thickness and rubber feel make holding it easier.
For screen protector, I went without on my SP1 and SP2. But always ended up with scratches, most very small, and maybe 2 cracks very small on each device. Nothing that affected anything, but I knew. With my SP3, I was going to go without once again. I had the idea of getting one tumbling around my head as I added this thick heavy case so might as well go all out, but ive never been a fan of screen protectors, so I never did. But, within 1 week, I noticed several very small scratches on the screen. So went to Best Buy and picked up the Zaag glass shield for SP3. Installed it twice (spider web cracked the first one while installing). But now that its on, I haven't noticed any additional glare or fingerprints, absolutely no pen problems (im on the pen 6-8 hours a day), and its really like its not even on.
I would recommend the Zaag glass screen cover to everyone. It doesn't add anything negative other than the $50 price. No glare/finger prints/pen problems/touch problems, nothing. And it only protects from those small scratches and nics.
