I'm all set to open an account with an exchange service. Mt gox seems to be the most popular but I wanted to know what the alternatives are. Thanks for any input

Thanks for the info man I appreciate it. And I'll look into the web based wallets to see which one is right for me

Hello,
 
Im new to this whole bitcoin world and I have some questions. Can you have a wallet on your iPad? How many posts do you need to have before you can trade things in the marketplace forum? What is the best exchange to buy and sell on? Any answers would be greatly appreciated.

Thanks
