More like, every Unix like system. Solaris, SunOS, HP-UX, AIX,
Irix, *BSD, and all linux distros have vi.
The same goes for learning sh (not bash, but real Bourne SH).

Just be careful not to get used to the X version of vim.
Also, vim supports a lot of extras, that othe unix versions
of vi do have. One that gets me a lot is, vim allows you
to move around in edit mode using the cursor keys, but
real vi doesn't. You must enter command mode to move.
Basic commands to know:
<ESC> switch to command mode
:q quit
:q! quit without saving
:w write file
j move cusor down
k move cusor up
h move cusor left
l move cusor right
i insert (before cursor)
I insert at beginning of line
A append at end of line
x delete char under cursor
dd delete line
u undo last edit
Those 13 will do most work. Other make life easier, like
<number><comamnd> do <command> <number> times
10dd = delete 10 lines
handy shortcuts
:wq or :ZZ save and exit
. repeat last command
