Review Sony Vaio VPC-Z21Q9E/B Subnotebook

Sony Vaio VPC-Z21M9E


All the above

2 keys have stuck and I need to get it mended. Less than a year old and very annoying. Not covered under warranty

Sony Vaio VPC-Z21M9E


Works well and performs as you would hope. Had it for about 18 months and it has, and continues, to serve me well

Upgrade to Windows 8 and it continues to work well - even quicker and smother but the Radeon graphics on the DVD drive no longer function, not a problem really but still annoying. Needs a hybrid driver and Sony don't seem to be producing one

Sony Vaio VPC-Z21M9E


excellent design, lightweight, SSD provides super fast boot time

Would have been better if the high performance grafix card was inbuilt into the laptop rather than having to connect the dock

Sony Vaio VPC-Z21M9E


Fast, good display, very convenient to take out as it is very light

Once the dock cut with power in a abnormail way, the laptop not working as well. Must restart all of them, not so clever
