Cons: Battery, Included Software, Software compatibility, windows 8.1
"Bought an i5 version from Amazon - good value. Very impressed with the build quality. I like things that have a quality feel and the U330 has that in spades.
Came with Windows 8 but support pages say that it is capable of running 8.1 and so I upgraded. Initially when the screen went to sleep it couldn't be woken without a hard reset. Updating the device drivers seems to have resolved this but there are other people in the Lenovo forum who have been less successful. I think that there are general issues around sleep mode with 8.1 and so this isn't necessarily a Lenovo thing but it need to get resolved or there will be a lot of returned units.
Overall I am very pleased with my purchase but await a fix to the sleep issue and I suppose I'l get used to the Window 8/8.1 interface."
