I'm sorry, but relying on Microsoft based products is getting for what you
asked for.  I know some people have wonderful uptimes with their Microsoft
systems, in particular running UIView.  However, those are few and far
between.  I have deployed several linux based floppies running aprsd and
have yet to have any of the failures you speak of.

Until someone can duplicate the feature set of Digined ala UIDIGI there's 
not much in the way of choices out there.  

I think ultimately the question comes down to, at what point do we want to 
switch to commodity hardware or keep purchasing TNC's whose lifespans in 
the big scheme of things are ultimately numbered?

Between Hansen's TNC and the potential for soundcard based TNC's there's 
really not much reason why we should continue down the path we've walked 
for much longer.  The obvious solution, if it can be made cheap enough is 
something with the smarts of digined that can interface with TNCX.  
Unfortunately I don't hear much in the way of people being ready or 
willing to offer up that solution.  If I were to do it I'd use computer 
hardware myself, mainly because I don't have much interest in learning PIC 
programming and all that comes with it.  As many have pointed out, 
computers with more than enough power are available for cheap, if not 

None of the answers are necessarily the best, but at some point we need to 
realize how we're cornering ourselves in the face of many many options.
