Neither is it an excuse for not dealing with recurrent problems when 
they become known: That is called procrastination or sloppiness.

Having a slight and partial technogical lead on some aspects of 
one's product is far from sufficient to ensure long term success. When 
selling professionnal ware, you need also professionnal attitudes, that 
is responsiveness and responsability, things Omega has not been too 
strong at.

If you cannot or don't want to afford the cost of being professionnal, 
that is perfectly OK, but then you play in the amateur ligue, and charge 
amateur prices for amateur products. Right now, for me TS is kind of in 
between for lack of rigor in its inherent design: SUPERB but a BIT 
SLOPPY at times hummmmh?

Mind though, Omega has come a long way, it used to be real sloppy with 
version 3.5! We can only hope to see the positive trend continue with 
TS5.0.

One becomes what one is putting in at every moment. If you don't 
respect your clients as equal partners, you will not become their 
equal partner, for they will not respect you either. It seems some of 
this must have been happening at some point, as I notice I am not the 
only one to have had too many frustrating experiences with Omega which 
had no reason to be, or to become such.
