It's an interesting point you make and may be true. But now show me a IT provider that doesn't over promise and under deliver or at the very least not have bugs in their code? They simply do not exist and have you ever tried to get Microsoft to fix their bugs?
That said I have no inbuilt loyalty to any IT provider, Draytek included and what they provide can easily be replaced. For me now, that'll be in 5 years time, unless they really screw things up!
Finally the point I was making was, compared to the last generation of Router up to and including the 2862, the 2927 is a vast improvement.
