I like you many years ago had a Tiny computer and had no problems with it. I think most people (though some wont admit it) started of with a Tiny. They were cheap and came with printer and scanner. I now have a Mesh and again have had no problem with it.
Regarding moans, it is very rarely you will get anyone saying "this is the best thing I have ever bought". It seems to be the norm for people to post there dissatisfaction than to send praise.
As far as e-mails go I have suffered the same responses as you. The dreaded no reply. Obviously the larger the company the more mail they will recieve. So I reckon they sift it out into two types. Reply or delete.
