I am looking for a good notebook which has all the three essentials, long battery life, less in weight and good on performance. I have found Toshiba Portege R500 to be a good one on all these parameters. Please advise on sourcing this noteboof from the net. Had anyone purchased from the net? If yes, please let me know the mail id or web address from where to source for a good price. Also if some other notebook which is better from the above one please mention.
