Hi there , I am about to buy a laptop but i havent been able to decide a brand/model. Can somebody suggest me a decent brand/model. My budget is about 60,000/-. How about Lenovo's 3000 N series. What if i want to get extra/optional devices in the given models. For ex 512 Ram instead of 256 or DVD writer instead of a combo. Please advice. Also can you also tell me what extra accessories are tob purchased and options/ features to be looked for.
