I upgrade from an old windows tablet the hp 2730p elite notebook to the sm-p600. I had windows tablet was designed for windows xp but I had 7 installed with 3gb of ram 60gb hard drive and that this new android tablet was better in every way except for storage space which can easily be remedied with a memory card.
Productivity wise the note 10.1 I would say is better in my experience especially since I have a spare wacom pen from my windows tablet that has the eraser on the back end that works perfectly with the note 10.1. Coding is a bit more difficult but I usually just remote desktop to my main pc and run Visual Studios. I have an otg cable with a usb hub for a hardware mouse and keyboard but haven't found a way to have the right mouse button in android to work as one instead of the back key.
Media wise the note 10.1 is better than my old windows tablet little to no lag full hd support and all that and hdmi out beats svideo out.
Gaming wise this is where I would consider upgrading to a windows tablet. As old as my hp 2730p notebook was I could still play minecraft (min settings 15fps), World of Warcraft (min settings windowed mode only 10fps) but at least Terraria played at a decent framerate 25fps+. On the note you have android ports of Minecraft and Terraria with touch controls in mind and being incompatible with the pc version. I would love something like http://forum.xda-developers.com/show....php?t=2209247
for the sm-p600. I have toyed with LinuxOnAndroid and hoping they make progress with a native gui vs vnc. Hell I would even dual boot with windows if I could.
Don't get me wrong there are great android games out there and the humble mobile bundles help but it seems like the good ports or versions are still on the iphone/ipad and android users are left with inferior products. Chu Chu Rockets for example has 1-4 player multiplayer support through bluetooth wifi and gamecenter and on the ipad 4 players can share one screen. So far on the android port multiplayer consists of 1 human and 3 cpus.
I have a few unrelated Samsung gripes with the note and I am not sure what I would upgrade to in the future.
