I tried several distros before and even liked them but had it been a faster machine the distros like pinguy OS are very good and beautiful indeed but for my Vostro they were just too bulky. WattOS does not come with any games at all nor does it have several of the applications that come with the standard Ubuntu distribution but comes with bare minimal of the applications only - for office they have AbiWord, Leafpad for text editior, KeepassX for password management, fotoxx for photo management, Firefox as the default browser (which i replaced with Chromium), and then you have the Synaptic Package manager to add any other that you want. I will be using this system mostly for Java development and programming stuff and not for any document editing at all (as for those i have a windows 7 desktop) so i wont care too much about how complete a desktop it has and i will prefer if it does not have too many extra apps that i will not use like at all. So i am happy with the speed and performance of the machine and feel like my old laptop is rejuvenated. I wish i had found such an OS as wattOS earlier without having to waste my time in trying out others. Now my CPU usage under similar load conditions as perviously described is around 3% and memory usage is 1% (i have 4GB RAM).
