Dear Eswar,
Before purchasing your Sun Blade 150 I suggest that you make sure that
it really performs better than a pentium for your type of application.
A while ago we were in a similar situation to yours, and we ended up
buying a sun blade. For our type of applications the Sun turned out to
be much slower, however. For example, we ran the same program (a st
cox) on both machines. On our old windows system (a P4, 1800 mhz) it
took 3 minutes and 45 seconds to complete. On the Sun it took more
than 12 minutes! We returned the Sun machine and bought the fastest
available intel machine with 2gb in ram instead. This still is slow
for some applications, but there is some comfort in knowing that it is
as fast as it gets.
Best,
Peter
