Just some personal considerations and one question...
First of all: I like mikrotik very much. However, I must note that it is necessary to look ahead to overcome current mikrotik limits in wireless, particularly in PtMP.
I mean: fixed line's competitors are leading to customers' house 30 or 50 Mbit, while the 5GHz spectrum is very dirty today. With current technology, in real environment, we can bring up to 20Mbit for a single AP when we're lucky.
Mikrotik seems doesn't offer any guarantees in wireless development...it is nearly blocked: no idea when we can have good filters, MU-MIMO, sync, better hardware, more bandwidth, etc...
A question to the Mikrotik's staff: do you believe in WISP's market yet?
