Yes the Dell Streak 5 also had a way to send a call straight to voice-mail and so does the original Galaxy Note.
But what I liked best was what people could do on the StarTAC 8000g.
The StarTAC 8000g had a way to immediately disconnect a call without sending them to voicemail and since I forwarded my home phone to my cell phone that option came in real handy to get rid of callers that had to be telemarketers. And if it was an important call they would just call right back since they couldn't figure out what happened.

As for the OP. My favorite apps are Google Maps, FoxFi, TuneIn Radio Pro, Slingplayer and Dish Anywhere but I have to use ES File Explorer and ASTRO to make installing and archiving of applications easier.
Note, I'm not real thrilled about the latest versions of FoxFi or TuneIn Radio Pro since they are both a step backwards for me so I use File managers to install previous versions of those two applications.
