With the endline for XP in sight I am considering dumping XP for Linux. I apologize in advance for my lack of knowledge in accomplishing this task. I have several questions I am sure smart Linux users can answer. 1) What version of Ubuntu will work on my 2004 vintage computer (motherboard: ASUS AZN8X2, 1.24 Ghz AMD Athlon processor, 2.5 Gb RAM) and current Linksys Wireless-G router. I believe I should use Ubuntu 12.04.4 LTS, but I am not sure. I plan to reformat an existing hard drive to use fresh with what I anticipate to be Ubuntu on an install CD/DVD disk. 2) Does Ubuntu come with some type of built-in browser? 3) Should I anticipate other compatibility issues/considerations before embarking on this transition? Thanks!
