Summary: I had many laptops/notebooks before but was looking for something I could use every day and travel with. This is probably as light as it can be, high-end specs and Windows 8.1 is now pretty good. No WIFI problems after Sony sent a fix and it doesn't get very hot. Yes, the fan is loud but it kicks in high gear only when the system is close to its limit (video rendering, for example). I got mine with 250GB of solid disk at a very good price from Amazon.
Summary: I got this laptop because I wanted a light, good looking computer with great battery life that is running on windows 7 ( I can't stand windows 8!!!). VIAO Pro SVP 1321 was the perfect choice! Anyways, this VIAO has a carbon fiber casing, it's only 2.3 pounds, it's lightening fast and it runs on windows 7 professional edition which is perfect! The battery life on this specific VIAO is truly amazing!!!
Summary: Have only had it a week. Very thin, sleek and light. Wish the screen would fold back a little further. Also, had problems with touchpad not working. Possibly an update caused the problem. Had to restore to a previous restore point to get it working again. Overall, very nice machine.
Summary: Had this laptop for about a month and so far it's been great. I haven't experienced much problems with WiFi. I had to go really far to get drop in speeds, to nearly the other end of the house. Similar drops were happening for my older laptop. Overall this ultrabook WiFi performed slightly less speedy than my older full sized laptop, but nothing too dramatic.
