My mom has been using the same celeron laptop with 1gb of ddr2 for years and its at the point where even web browsing is painful. She told me to look for a new one for up to 400euros and i came here for help. I immediatly thought core i3 cause im not familiar with pentiums and celerons. For just facebook and maybe 720p youtube from time to time what can u recommend? Please dont link me sales at best buy and stuff case im not in the us. Ideal for me would be this website https/www.skroutz.gr/c/25/laptop.html?from=families
