Okay, here is an update on day 3: I did get Konquerquer confused and stuck on a form a couple of times and also crashed it two other times. I've discovered that KSpread always crashes when you tamper with precision setting in the format-cell window. Galeon has been great so far except some quirky behavior navigating your file system from the "save" screen while attempting to preserve the original filename. Both Abiword and Kwrite mostly destroy the formating of an MS Word document that has any complexity, but can handle simple stuff okay. MPG321 has been substituted for MPG123 and segfaults after playing anything (on my system anyway). Finally those cool root window fantasy pictures have disappeared from e-term & enlighenment WM.

Still, I really like my new Slackware system.

I have not seen any of the applications that you mention work perfectly in all scenarios on any distribution. Some of the code is not even in Debian (except unstable "SID") because of this.

Just since Slackware 8.1 came out, KDE 3.0.2 has come out and it addresses a few of the problems mentioned with respect to KDE issues.

As far as document compatibility, nobody can seem to keep up perfectly with Microsoft. It seems that they deliberately keep changing file and document formats to keep competitors from re-engineering their work on any more than a superficial level.

Playing video and movie files is another common and problematical area. I expect it to improve, but the problems are not unique to Slackware.

So far, the issues you've found are pretty common ones, and you're right, they are not unique to Slackware.
