If the cost is not prohibitive, you might consider a mini-computer. Acer, Asus, HP and Dell make small, light, mobile computers that cost from $350 to $500. The Acer Aspire One Netbook is probably the least expensive and could handle your Flip videos. A 6 cell battery is optional and lasts for 5 to 6 hours on a charge. But then there is the problem of charging it in India. Good luck!
