Get an Ethereum Wallet
Ethereum is still quite new and has a smaller userbase than Bitcoin. The best Ether exchange is Kraken because it has the best reputation and volume in the Bitcoin/Ether, USD/Ether and EUR/Ether pairs. Ether wallet options are somewhat limited, although its passionate user base has already created a few decent wallet options.
Ethereum Wallet
Ethereum Wallet is a desktop Ethereum wallet. Ethereum Wallet has integrated with ShapeShift, which makes it easy to accept Bitcoin and other altcoin payments directly to your Ethereum Wallet as ether.
Geth
Geth is a command line interface for using, sending, receiving, and creating contracts with Ethereum. Geth is a good option for programmers, but not a good option for users in search of an easy-to-use wallet.
Etherwall
Install Etherwall with Geth to transact directly with the Ethereum network through Geth, but with an easy to use interface provided by Etherwall.
MyEtherWallet
MyEtherWallet is an open source Javascript client-side Ether wallet. MyEtherWallet makes it easy to create secure wallets without the command line or the need to run an Ethereum client on your computer. By running MyEtherWallet on an offline computer, you can create secure paper wallets for your ether holdings.
MyEtherWallet also has a Chrome extension in beta that adds a better user interface for sending and receiving transactions.
EthereumWallet
EthereumWallet is an ether wallet by Kryptokit. Much like Kryptokit's RushWallet or MyEtherWallet, EthereumWallet uses client side Javascript to quickly create Ethereum addresses in web browsers. EthereumWallet is still in beta and should not be used to store large amounts of ether.
EthAddress
EthAddress is another open source Javascript client-side Ether wallet. It supports single wallets, bulk wallets, brain wallets, vanity wallets, and split wallets.
