I bought this Laptop (not from flipkart). If you are buying it for the purpose of heavy gaming then I would not recommend it but still this laptop has a potential of being satisfactory in nearly all other tasks (It easily handled half life 2 episode 1). Running 1080p HD movies could be a bit problematic but 720p works just fine. A good battery back up of >= 3 hrs. Windows Experience Index - 4.5 I would strongly recommend it for students.
I bought it along with 4GB RAM. Checked with Tech support people for RAM compatibility and they were quite co-operative. Installed Ubuntu 11x 64 bit and side by side Windows 7. Working fine for last 3 months :-). No issues.
