FWIW, I use both, with hotkeys to launch whichever I want.

If you haven't used krunner in awhile, consider trying it for a few
things.  You might be pleasantly surprised.

For instance, need the result of some simple math?  Type it into krunner
like so (here I'm converting the day's forcasted high from Celsius, which
I'm trying to get familiar with and thus have the weather applet
configured to display, to Fahrenheit).

32*1.8+32=

krunner gives me the result, 89.6F. No need to open a real calculator. =:^)

(Of course, doing it in my head, I'd simply double the 32 to 64, move a
decimal, 6.4, and subtract, giving me the 1.8 multiplier, 64-6.4=57.6,
calculator for that, but it illustrates the point.)

Or... how long should a 4.2 GB DVD image take to download at my new rated

4.2 GB (2^10) * 8bit/Mb (10^3)/s /15 (multiplier)
4.2*1024*1024*1024*8/1000/1000/60/15=

Just over 40 minutes @ 15 Mbit/sec

... change the 15 to 12...

Just over 50 minutes @ 12 Mbit/sec

Accounting for overhead, figure 45-50 minutes vs an hour.

Krunner looks for that terminating equals and throws up a result when it
sees it and the stuff before it looks like a math expression. =:^)

Then there's the example I first used.  If you type a dotted address that
looks like either an IP address or domain into krunner, it'll give you the
choice of opening it in whatever the kde-default browser is (konqueror,
here).

But, it also searches konqueror's bookmarks and offers any that match as

Then there's the web shortcuts.  A number of them (like gg:search term,
for google) are on by default.  So you can enter gg: and a search term
directly in krunner, and it'll give you the choice of opening a google
search for that term in, again, the kde configured browser.

It's possible to setup your own shortcuts.  By default, ggl: sends you to
the google's I'm feeling lucky top-hit page, but I never use that, while I
changed the default ggl: entry to be a google/linux search here.  By
default there's entries for the kde bug database (tho I'm not sure they're
actually active by default).  I have those, but I use custom entries for
the Gentoo bug database more.  There's a wikipedia shortcut (wp:)
available by default.  Etc.

Web shortcuts can be used in either the konqueror address bar or in
krunner.  They're configured in konqueror's config dialog, web shortcuts
config applet.

If you have the semantic desktop active, and the krunner applet that uses
it (both of which I have turned off, here), typing parts of an email
subject will let you open it.

Typing a path, for instance /usr/share, gives you the option to open it in
kde's configured default file manager (dolphin by default, but it can be
konqueror or gwenview or...).

So yeah, I use krunner reasonably frequently, especially for stuff that I
don't need the STDOUT/STDERR from.  But I use konsole a lot as well.  For
file management and text editing with my sysadmin hat on, I actually
prefer mc, opened either in konsole or at a CLI login outside of X, to a
graphical file manager or text editor like konqueror/dolphin or kwrite.
Being a Gentooer, I do all my package management, building, etc, at the
CLI, again, either in a konsole window or at a CLI login outside X.  Etc.

So I use both krunner and konsole, for different things. =:^)
