I have never owned a laptop and I don't know anything about them. I don't need to worry about memory because I have a 500gb external hard drive. Screen size doesn't matter that much (as long as its not below 15 inches) , and neither does weight or battery life, but I don't want something too slow because i often use msn and flight sim X. I also don't want to spend much over £250 ($380ish), can anyone help?
