choosing an os is not an exact science.
dapat depende iyan sa kailangan mo at kung ano ang kaya mo.
windows xp - if you just want something that would make you do office applications, surf the net and play games without worrying about anything. of course because you don't worry about anything, you have to pay somebody to do the worrying for you that's why napaka-mahal ng licensed software.
dahil sikat, palaging ina-atake ng virus.
gnu linux - open source and free. good for people that like to know everything that's going on inside the box. for those who like to tweak and customize. pwede ma tweak to whatever specification you want or need. kaya lang dapat enthusiastic kang mag DIY. at dahil hindi pa masyadong sikat, hindi masyado ginagawan ng viruses.
Hindi masyado ma-appreciate sa 'pinas ang gnu linux dahil its best feature of being free is not really that great in the eyes of users who use pirated windows OS. Siguro kung small business owner ka at kailangan na licensed ang software mo para hindi kag ma raid ng OMB ngunit kapos ka sa capital or kailangan mo lang magcost cutting, dun na siguro papasok ang linux.
also, kung gamer ka, ma-iinis ka lang sa linux.
