In regards to the KDE 4, of course there are going to be issues with it right off. After all, it was only just released. Also, remember, the only way to improve it isn't to sit and whine and tell everyone NOT to use it because it BREAKS, it's to help out, submit suggestions, help with artwork, do some bug reporting, troubleshooting, even try your hand at submitting patches ( if you're good enough, which i'm not)
Mind you, the last time i used KDE4 it was very very broken, but that's because I jumped on the bandwagon when that alpha version, the version where stuff is expected to be broken.
Side note: Ever notice how many stable useful linux apps aren't even version 1.0.0 yet?
Back on topic, I'm using Granular, as it's a PCLOS derivative, and it's fast, stable, and does what i need. It supports my Broadcom wifi card, all i needed to supply were the firmware files.
The only thing that i find to be a slight issue is that the kernel is compiled to be optimized for server usage, which is fine i guess, except for me needing to do various video editing and all, lol.
And i always recompile the kernel when a new one comes out, to remove unneeded stuff for my laptop, to make stuff faster. (alright, i admit it, i'm a geek.)
Anyways, I can say that although it is quite silvery (i like that tho^_^ request: gold theme for next release?) it is nice, solid, and fast.
Keep up the great work, guys!
