The build quality of the Surface laptop keyboard is appalling. My space bar and caps key cracked when the machine was still in warranty. MS refused to replace the keyboard and wanted me to buy a replacement baseboard for £500. I have been using coloured electrical tape to protect the cracked keys for over two years. My space bar is now almost unusable and MS now say they don't sell replacement keyboards anymore. I am now two months into a wait for a replacement keyboard ordered through a laptop repair shop
The Surface Book is the fastest most reliable laptop I have owned but the design flaw with the keyboard will lose MS customers because people will correctly conclude MS value profits over customer service and the environmental cost of its fragile, non replaceable keyboards.
