I have a two week old Aspire 1 with 1GB memory and 120 GB HDD. My problem is the linux operating system and my absolute lack of knowledge in Linux. Doing my head in trying to put software on and dealing with the never ending dependancy problems. I have decided to move back to MS. My home PC is on Vista and I have a disc for this. Some question for those who know better than me. 1 - How easy is it to replace Linux and put MS on instead? 2 - Is it better to put XP or Vista on? (Will Vista be too memory hungry?)
