Lenovo is one of the laptop with which I m working since 2011. Its been a great laptop and this model being one if the best model till date.Lenovo is the only model which I will prefer and will use because its processing speed and capacity is much better and higher than other models like Acer and HP. I tried working with those model too but this dell model I felt is one of the best amoungst all. I will still recommend you and and will try to google all its feature. I and happy with Ideapad and will recommend everyone for the same.
