Other apps like Opera Mini or certain IM applications can use Wi-Fi directly. That means it's just like a wireless connection on a laptop or netbook. No need for RIM's servers.
Wi-Fi is far faster than 3G, 4G, whatever else. Nothing comes close.
As for coverage, there are many cases where Wi-Fi is available when regular radio signals are not. Where I work is one such case. I have no idea if the S2 has UMA, but if it does then you'll see the advantage right away.
