Things I have that I may or may not have bought for the pro, but happen to have it
USB 3.0 external hard drive
USB 3.0 Thumb Drive
64gb Sandisk Micro SDXC
Bluetooth Wireless Portable Speakers
Bluetooth Wireless Mouse (To Spare an extra USB Port)
Cyan Touch Cover
Portable Bluetooth Keyboard for when I want to do serious typing
Minidisplay port to VGA Adaptor for projectors and monitors (Hoping a cheap one I bought online will work)
Things I thought of but decided best not to get:
-Screen protector. I generally don't like screen protectors. Since the surface pro boasts a great digital inking experience with very little gap between the glass and screen due to it being optically bonded, so I don't want a screen protector adding more gap between the digitizer and the screen. I also don't like the "privacy" screen protector that defeats the purpose of having minimal glare and excellent viewing angles. The surface rt/pro is supposed to have one of the best if not the best screens on the market in terms of viewing angles/minimal glare. Better than the Ipad and other similar products
-Folio Case. It would probably cover the kick stand and make it useless, which is one of the surface's biggest selling points. It will probably trap more heat as well. The magnesium casing should be durable enough along with the protective touch cover. I can easily just put the surface in my backpack or my laptop case. I have had my laptop for a long time and use it on the road a lot and there are almost no signs of scratches, wear, etc. I'll just take care of my surface the way I took care of my laptop.
