If you're on Windows or Linux, but want a safe, but lighter alternative to the Bitcoin client (no blockchain download required!), you can also try out Electrum... I bet you'll like it!
I've also started to maintain a
quick comparison chart for Bitcoin wallet clients for the desktop. Hopefully it will help you choose what's best for you. All the clients listed in the chart are open source and recommended by the official bitcoin.org website (at
that page)
just one issue with your chart, the
Fast sync (<1min)
section, technically Multi-bit or Electrum don't have any sync. Electrum just queries it's server to get the lastest blockchain information and multi-bit just doesn't worry about blockchain before the address were created. So honestly that isn't syncing it more of how they handle the blockchains.
