nah, the 400 is a good box. this is coming from a guy who's programmed on one for over 5 years now

you can upgrade the crap out of them, from a variety of sources. jhu is right; they're expensive. an decent box will run you about as much as a tricked-out PC server($12000). i can honestly say after doing some work on a UNIX box(variety of flavors), PCs & the 400, the 400 is the easiest to use.
