Although technically a lot of complaints in this topic have a basis somewhere I don't really understand the complaints about the RB4011 series.
For anyone who has a 500Mbit or a 1Gbit Internet connection coming into their home/business and who wants to do routing between internal subnets above 1Gbps and have some CAPSman AP's connected, the 4011 series seems like a great device! I'm running a CCR1009 personally, but if I wasn't I would buy a RB4011 in a heartbeat. In some tasks it will actually outperform the CCR1009 because of the higher single threaded performance.
So performance wise it should be steller for a great price. Passive cooling is good and although the switch doesn't seem to support VLANs with the amount of power this thing has, doing a few Gigabit through the CPU shouldn't really be an issue? Better then getting a similarly priced UBNT device where if you enable certain features you're speed drops through the floor.
It doesn't have an USB port. Could have been nice, be in all honesty the amount of times I've used one is rare, very rare. If we now have to buy a cheap Routerboard LTE device for that, that's ok.
And the LCD. I have lots of Mikrotik's with LCD's, you use them never. Do you want to pay a 10$ (or whatever the cost is) premium for that? Generally the answer would be no for most people.
Then speaking of the wireless version, it's the first Mikrotik 4 chain device and has external antennas again so I'm really curious how it will perform.
Complaints like "the wireless can go up to 1733Mbit so you need more 10Gbit" I just don't get. If you know anything about wireless you know you can't compare stated wireless speed with cable speeds. And even if you could, 90% of devices out there only have 2 chains. Certain Macbooks are exceptions and have 3 chains, but that's a rarity. So that theoretical speed, you're never going to achieve that. Wireless still isn't as fast as a cable, no matter what it says on the box. Maybe in an ideal situation using both the 5Ghz radio and 2.4Ghz radio you could come close to 1Gbps of real throughput, maybe.... Not until 60Ghz wireless becomes a common thing do you need to worry about the speed of your wired ports.
Then what use is 4 antennas? Beamforming and other features can make great use of it, especially in situations where multiple (2 chain) clients are connected, overall speed will remain higher, which is good.
So maybe I'm missing some big points here but to me this RB4011 looks great for small business use or in a more demanding home situations. Plenty of power and passively cooled, great! I also really like that it can do hardware AES so you can tunnel all your traffic through a VPN tunnel in a work related situation or at home through PIA or something like that!
This is my opinion, and I'm sure there are use cases where this device doesn't suit the need, but I just wanted to show some positive excited thoughts about it instead of the bad reception it's been getting.
p.s. I just read that it might not support passive DAC cables in the SFP+ slot? If that turns out to be true that would be a big missing feature in my opinion.
