3G matters for lots of different reasons. Not only is HSPDA good for fast browsing and other data intensive applications like email, it also has the ability to use data and voice at the same time. I don't know one business user of BlackBerry that would not love voice and data simultaniously. If I am on a long 2 hour conversation using my Bluetooth headset, I would LOVE to be able to get an important email at the time it was sent, rather than 2 hours later after I am done with my voice call. When it comes out for AT&T people will wonder how they survived without it based on that aspect alone. I can't wait for an HSPDA BlackBerry just for that alone. And I know of a few people who switched to a Windows Mobile device and BlackBerry Connect just so they can keep up with their important emails WHILE talking on the phone to an important client for an hour or two.

So yeah ... HSPDA on a BlackBerry matters a lot.
