Headshotgamer posted a review on Kubuntu 8.10 Alpha 4

You're probably wondering why I'm reviewing Kubuntu 8.10 Alpha 4, when I've already reviewed Ubuntu 8.10 Alpha 4 – both of these distributions are looking at the same 'Intrepid Ibex' repositories and therefore have access to exactly the same kernels, proprietary drivers and games. The answer is simple; it's using KDE and not Gnome, and I don't believe Kubuntu gets the attention that they deserve. Truth be told, Kubuntu was the first of the “buntu's” that I tried and it remained my primary distribution for nearly a year (a very long time for me). Apart from the window manager and the programs that they're bundled with, the differences between the “buntu's” is extremely minimal (pretty much limited to different user groups, CDs, artwork, fanbois).
