1) attention, it has no bluetooth as announced in the title of the offer amazon
2) a webcam of 0.3 Megapixels, a pity that great brand like Sony does not allow to devices with images of very good qualities.
3) the battery is announced 4,5h autonomy, but I'm not going further than 2.5h in Energy Saving Mode
For the positive:
It is light, 2.7kg it's not heavy.
Its 500GB hard drive and performance, it's fast.
Easy to use, easy grip.
Windows 7, it's great.
Good sound and wireless works great.
