Summary: In the description of this product, it states that the OS is "Genuine Windows® 8 Professional 64 bit". The tablet/laptop I received had Windows 8 (regular version) on it. I did not realize that the wrong OS was installed until after installing Office 2013 and other software. I asked the vendor (Tek Depot via Amazon) if they could send a code for Windows 8 Pro since that what I paid for.
Summary: I've had this laptop for all of 2 terms now (about 7 months) and it's driving me crazy. Firstly the battery life - 3 or 4 hours at most - isn't enough to get me through a whole day of uni. Carry the charger on you or buy an external battery. I called up Lenovo asking for a fix and they said oh no it's fine. Secondly, it frequently freezes up for a few seconds, returning a "Firefox/MS Word/whichever programme you're using is not responding" message.
