Hey friends! This is the personal experience on samsung laptop. The laptop model is rv509 which I took in 2012 now its been around 4 to 5 years. The laptop I have comes with standard specification. It has 4GB RAM and 500GB HDD. It has core i3 intel processor, good resolution screen. The keys are well fabricated, so it is easy to type and play games. The os is windows 7 ultimate, it has very impressive speaker, front camera with less megapixels, which is not clear.
Talking about battery backup the laptop used to give me full staright 4 hours usage on full charge. Now its giving 1 hr to 2 hr.
Playing games, browsing battery drains fast.
The laptop is fat and weight, comparing with present laptops, it has 3 USB slots, mp3 jack for headfones, charger slots, RJ45 cable slot.microSD card slot, and CD drive. So considering the above features and usage and my experince on this laptop, it is above average, so any one who wants to buy samsung laptops can go for new models which has more good features then this. The cost of this laptop I paid was 28000 in indian rupees.
