If producer kills the product or goes out of business whatsoever, you're grounded. You may even be unable to migrate data to other system or migration could be very, very painful. You most probably won't be able to integrate it with any of your systems except maybe for big, very expensive ones that happen to be popular. > Not to mention it would have been tested better. Except when it wouldn't. I've seen such cases, and they are not that rare when it comes to systems that are not general purpose. To all this add the fact that by buying a system you totally loose the control over bugs in it. You may be hit by a subtle bug that is a show-stopper for you and the producer may refuse to fix it, claiming it to be low-impact.
