Hi, my old laptop has finally given up the ghost so I'm looking to buy a new one to run my small home based business from. I need MS Word and Excel, social media, and internet - nothing flashy. My budget is anything up to £400 (ideally around the £250-300 mark) I've always gone for something with a Pentium processor in the past but wondered if the other processors (which seem to make the laptop cheaper) will be enough for what I want my laptop to do. TIA :)
