I hear a lot of things too but I tend to do my own homework and make my own decisions.
You are going to be on a Hub3 someday and the issue is soon to be fixed by an "Intel" firmware, for now if you aint pro gaming online the jitter will not cause any issue and miens is pretty good regardless (look in my gallery).
I can say myself to iv had the hub 3 for about 4 months now with the gamer bundle and there is no real problems. (Only had 2 random reboots in the first month, must of been updates) So all the bugs the hub 3 had to start off with must have been fixed.
"As it currently stands the amount it affects you depends on a number of factors. Whether or not you do any latency reliant stuff (gaming being the main thing that people mention)."
As it stands, SH3 has between 1%-7% of DNS queries fail. Use the GRC DNS checker and see for yourself. That impacts everyone. You might not realise that why you sometime have to reload webpages, and experience weird behaviour but everyone using an SH3 is likely impacted by it's issues...
