Summary: When I get this notebooks, I feel really sorry that Vaio Z series is gone. Nothing really wrong with this notebook, except, maybe, some lack of USB ports. But if expect to get top-level business laptop, with quality and nobleness of Z series Sony - you would be disappointed, as I was.
Pros: Super light and fast, startup is similar to wake from sleep on older laptops.
Cons: Very buggy! I've gotten the BSOD 3 or 4 times a day since my second week of owning the laptop, often losing important work done in between saves. Does not wake from sleep well and will often restart without being prompted. I flashed the BIOS but am still getting BSOD often. Tried to return to Son...
Summary: silver paint over it is very poor quality. it came off immediately after a minor touch with its own adapter. one will buy this computer because of is its portability, but because it has so little resistance to scratches and touching, you cannot put it on a hard surface.
Pros: really light
Cons: 1. capricious - does not bother reading from external hard drives which other older machines read fluently. needs everything perfect. 2. silver color comes off easily. 1 day old looks like 2 years old 3. 128 gb. is not enough for the sizes of software we need to download nowadays.
