I have downloaded it and run it in a USB drive via UNetBootin. I don’t know yet if my previous problem with Kubuntu 9.04 has disappeared (after installing proprietary video drivers, sound in Flash disappears) but I have some comments that might improve the KDE CE experience.
1. The bootsplash doesn’t looks good. Kubuntu, with it’s thin blue progress bar was way better. My suggestion is apply some aesthetic makeover.
2. While the desktop is loading, several icons appear (I don’t know what this process is called.) Now the icons are good, but then the LM KDE CE appears and it seems out of place. It’s larger than the rest and sticks out badly because it doesn’t look up to date. I suggest a remake of the LM icon for the KDE CE.
3. I have tried LM 7 and I find the Mint Menu excellent. Everything is well placed and well thought of. Perhaps a similar menu can be implemented in KDE CE.
4. Last but not the least, I suggest a program similar to Mint Install that will take care of how the desktop looks and feels. Some customized themes that bundles complementary icons, wallpaper, etc should be available from the start (perhaps selected upon install?), and downloadable themes should be made available. The reason for this is that I, like many new users to Linux, feel that the appearance is not modern enough. KDE 4 looks modern, and I think by implementing customized themes, it’ll be better because the new user won’t be forced to hunt down HOW to do it. I look at some user’s customized desktops and turn green with envy.
My suggestions are mainly aesthetic in nature, but I guess these strike at the heart of what Linux Mint exhorts: elegance.
