SCO Unix vs ICS vs Xenix

[Willy Paine]

I have contacted several people on private personal opinion on comparing
between Xenix and SCO UNIX on performance and price.  Now I am trying to
find out between SCO Unix and ICS 386/xi 2.0+.   I am told that SCO Unix
is slower or more clumsy than Xenix and couple of SCO Unix owners are so
UNempressing with SCO Unix performance.   Some said the kernel is too
big and using too much memory that don't allow enough memory for
X-sight.   I have the latest verison Xenix and ICS 386/ix and they are 
different on size and performance but I am curious about SCO Unix vs ICS 
386/ix.   One person is saying that ICS 386/ix is better product than
new SCO Unix but I can not tell if he already test with 386/ix.
I am still checking on upgrade cost.  I think upgrade cost could be too
expensive that this is rather close to distributor's price on buying brand
new SCO Unix.  There are two difference choice, 2 users and unlimited
users.   I think 2 users product is a rip off because I have past experience
with 2 users version.  If I add mouse in one port or run another virtual
tty (this was old ICS 1.06), it screws up the whole system but I have not 
tried the latest version on 2 users product.

SCO Product Support have improved quiet a bit over a year ago and I am
very please with fast response and I think SCO is good reputation as
being old and stable company on Unix for micros.  Major disadvantage is
really high prices.    ICS is agressive company with good effortable
discount on Unix close to real System V standard but is rather flaky on 
fixing products.

p.s.  This is my own opinion and I am running Xenix/386 and ICS at home.
      My company has nothing to do with these at all......
