My 4 year on Sansung desktop/laptop is showing signs of possible failure. My budget is £500 & I have selected a number of possible replacements, they are in my wish list in Amazon UK. I would be grateful if the techies among memebrs would give them the once over & let me know what they think.http://www.amazon.co.uk/gp/registry/wishlist/ref=wish_list Yachtsman1.
