This is pretty close to being a decent machine but I don't really want a tablet/laptop hybrid so all the compromises that have been made to make that possible are just going to annoy me. Give me a 1080p screen on either an 11.6" or 13.3" laptop with 8GB Ram and either a 256GB SSD for a sensible price or a cheap 2.5" HDD that I can swap out myself.
If you want to upgrade this Vaio from a 128GB SSD to 256GB the cost is £250 !!! At a time when a decent 256GB SSD is £130 and top of the range is less than £200. Sony want £250 for an upgrade.
