Well, could you explain why do you think so? Like I do below...
The linux scheme of putting everything in /dev positively sux (SIC).
It slows down device name lookups and (even more so) programs that
allocate ptys, or map major/minor numbers to tty names (like ps),
or use isatty(), ttyname(), etc. And /dev will only grow - there
are about 1000 entries on my system right now. I didn't remove the
unneded ones (everything as shipped with Debian 1.1) - but then,
I still have only 64 and not 256 ptys (2 devices each).
Besides, it's not just Sun - I have seen this on HP-UX as well, SCO
uses different names but in /dev/dsk too. I believe they did that
for a reason, not just to make things suck more positively :-).

Except for the examples given above...
