As a Canadian, I can't use Google Voice in order to send my SMS. However, there are numerous apps that act very similarly, including the new DeskSMS from the developer who brought you ClockworkMod.
DeskSMS transfers SMS to both your e-mail and other IM applications through the use of your Google Account. This allows you to answer SMS on-the-go and with the use of a full keyboard. As someone with big fingers, I can't tell you how annoying it is to try to do a large amount of typing with an on-screen keyboard. This definitely helps.
The app is in free beta, but presumably won't stay that way forever.

Last month we had the chance to play around with LauncherPro developer Fredrico Carnales' latest app, UberMusic. I, personally, had a great amount of fun with it, as it evokes a certain "Zune" feel while remaining largely functional.
The app's left its open beta phase and is now available on the Android market for a price of $3.49; for a music player that pulls in album art and artist data, I'd say that isn't too bad of a price.
It also looks like there's been some UI changes to the Artist and Album sorting, as well. Albums show up with their art individually, and everything looks a whole lot cleaner.
