Money, money, money

Today we had a visit from a family friend who travelled extensively in his youth.  He couldn't believe I would just be travelling using credit cards.  To be honest I hadn't even thought far enough ahead as to how I was going to pay for things in India.  He suggested traveller's cheques which I was told by several people were obsolete.  I started research right away and people in forums and on blogs say don't bring cash, don't use credit cards, and don't bring traveller's cheques! Um okay....so what's left?  Sounds like I need to do a little more research and poll my friends! ;)  Let me know if you have an opinion on how to carry/get money in India, China, and South East Asia!!! 
There always seems to be something new to think about!
On another note, this time next week I'll be enroute to Munich! Wow! :)
