KDE4 runs on 40% less memory than KDE3

KDE4 which is a windows manager system for Linux is reported to consume forty percent less memory than the previous version of KDE3.5 and this is without so-called “mini-optimizations” yet they have beefed up the look and feel of the windows manager. One of the developers even tested KDE4 on a 256M and 1Ghz machine specification to see if it could actually function decently.
Strangely enough, if you take the comparative Microsoft’s latest “achievement” in Windows Vista, the look and feel definitely has increased but so has the consumption of resources.
In layman’s terms, this basically means… linux can be used on older hardware without giving up the look and feel of newer software. How’s that for change?
