Normis you sound like there is nothing wrong with RB2011xx at all...
Apart from the mentioned issues with case design, what else is wrong with it?
1. 2011L routers became stable with 6.2 (after cca. 1 year since production started)
2. 4 our of 6 routers 2011L that we bought were randomly rebooting, 1 went completelly dead after installing 6.2 with netinstall and is totally locked, we took others out of production
3. case design is such that you need it to unscrew in order to unplug ac/dc adapter (i hear this will or has already been changed)
I agree and I know that techical stuff is subject to have errors out of the box also. But, the Asus made no problems regarding warranty, Mikrotik almost always did. Remember the capacitor problems with 411 series? Mikrotik declined all warranties. We had to change the capacitors ourselves (200 units!) and this I will never forget.
I total I love Mikrotiks, but 2011xx didn't came close to satisfying me.
