Re: "the system has a more modern and 'flatter' look"
"I used to really love KDE, but it sadly lost its way from version 4 onwards, requiring a graphics chipset with quite some oomph at a time when many computers still didn't have one, making it (for the time) bloated and slow."
I keep hearing this, but my reality doesn't match the griping. I installed Slackware 13.0 on a (then) 6 year old laptop in 2009. It came with KDE 4.x. The laptop in question (HP zv5105) has low-end Intel graphics with "shared" 64megs of memory. It ran KDE 4.x quite nicely, and was my primary computer for 7 years.
