Welcome to Linux Lite. The finely tuned race car of linux distros.

No other OS that I've tried has run as smoothly (both speed and problem-free) as my previous XP installation on my old Dell Inspiron 5100 laptop - Pentium 4 2.4GHz, 512MB RAM, 30GB HDD, 16MB ATI Mobility Radeon 7500 graphics.
I had reduced the XP Installation Disk to one third (3xxMB) of it's size using nLite. I then performed tweaks (for speed and stability) to the system and finally tweaked individual programs.
Linux Lite runs just as well (maybe a
fraction slower in some areas) straight out of the box. The Live CD also worked on a couple of work PC's that had problems with other distros in the past. And everything is still running smoothly after 6 months and an upgrade to LL 2.0.
And as you say, it is constantly being improved including new sections to the Help Manual.
When I finally upgrade my PC I will be installing Linux Lite as my main OS. The work the Linux Lite team have done "under the hood" to make it run so smoothly on older hardware is amazing. And the more modern hardware will enable me to run Steam and XBMC, things I cannot do at present.
