- I think you'll find a 486DX/66 much faster than any Sun you'd consider
- buying. Of course, the speed depends on the OS as well. I'm
- currently running Linux on a 386/25, and response time is better than
- the Suns we have at school. Of course, the processor is slower (I
- think), and the disk is certainly slower (I have an IDE), so if you
- have computationally intensive tasks or large data-bases, you'll see a
- difference. On the other hand, because Linux is SO well designed,
- almost everything else runs FASTER. I'm not running X, but I
- understand that with 8MEG X runs in real time even on 386/25's.

- On the contrary. The free implementations are better, IMHO. Linux is
- certainly more stable (even though it's still in bet 0.98), has MUCH
- MUCH better support, comes with source code, etc. People are even
- working on detailed and comprehensvie documentation. Linux seems to
- be the fastest Unix available. 386bsd currently has better network
- support. SCO Unix has a better DOS emulator, and a fancier windowing
- environment under X. SCO Unix with those features also costs about
- $2000 more than Linux (which is free), for which price you may as well
- buy another computer to run your DOS apps. on....

- I have a 386/25, with 6MEG, and two IDE drives for a total of about
- 200MEG for Linux. I get VERY good performance. I'm not running X,
- but I can run GCC via make in an Emacs window while I'm downingloading
- something and still get great response time.

- Zeos makes very good equipment, and you can't beet the price. I
- purchase from Dell, because their support is better (at least, it was
- when I bought my computer). Over the summer, my computer was zapped
- by lightning in a remote location in New York State. Dell came
- through, and arrived the very next day with a new motherboard, and
- replaced the whole thing. Dell's computers are also built better than
- Zeos, as they invest more in R&D. But I don't think you'll really
- notice the difference there.
