I assure you that the Internet is changing from RPM packager to deb. I had this PC that rejected RPM distros, yet worked with Ubuntu distros. I had to get away from Unity in Ubuntu 11.04, because it is more work and buggy. Linux Mint 11 keeps on using Gnome 2.32.1 or Linux Mint 12 with Gnome 3.0. The biggest app for Linux Mint 11 is The Gimp image editor which was absent since Ubuntu 9.10. The 2nd biggest is VLC Media Player 1.0.9. Some worth while upgrades from Ubuntu 10.10 is the new Out-of-Memory (OOM) killer, AppArmor, improved threads, faster Ext4 file system, faster desktop environment reaction speed, and Find command executed with filled caches faster. I know that Firefox 3.6.5 in Ubuntu 10.10 was more stable than Firefox 4.0.1. The Software manager is easy to use, my first selection is "Gnome Games". Linux Mint 11 is definitely more stable than Windows 7 SP1 since Windows 7 SP1 crashed on me for no reason.
It's about a 9.5/10
Sun Java 6
VLC Media Player
Either Linux Mint or MEPIS is the best debian/Ubuntu distro. OpenSuse DVD (my #1) comes with 5 times as much software as Linux Mint 11 .
