I bought the Lenovo G50-80 Notebook and I am using this pas 6 months.
And trust me this is what I was looking for. It has the i5 processor with 2.40 GHZ help run its smooth with its 1TB hard disk. Also the 8GB SD Ram its makes thing to easy for me. Every things runs very smooth from last 6 months I have had no issue or challenges.
The Dolby Speaker are good enough for a single room to pump it up so full marks for it. Very nice quality of webcam which I personally needed the most otherwise I had to purchase a manual one from outside. Easy skype and hd web calling.
Battery also is not a challange till from in past 6 months gives a fair back up of 4 hours which is more than sufficient.
