In response to your request for "1) An equivalent of iPhone Dragon Dictation."...
Speech to text is a wonderful service that smart phones offer and Android has some terrific solutions. I use speech to text very often, so I'm glad to share my experience.
The built in Google Speech to text is good, but has it's limitations. First, it stops whenever you stop speaking. So, if you pause, it will translate what you have said, but you may want it to go on. Second, it does a poor job with capitalization and punctuation. Third, it's not available on the Swype keyboard.
You need to two solutions for Speech to Text on you Android phone. First, Vlingo Virtual Assistant by Vlingo Corp. (free). This App allows you to bark out commands starting by pressing an icon on you home screen or using the InCar feature. I use it to give commands like: Call Home, Navigate to Ralphs, Text Message or Email to Joan and then dictate the message. And much, much more.
The other area is dictating text in any App where you want to enter text, such as email, SMS, notes, Word, Calendar, etc. For this I use the FlextT9 Speak-Trace-Write-Tap App by Nuance Communications, Inc. ($4.99). I was a huge Swype fan and was an expert at it. But I had to have voice to text so I tried this. This is by far the best keyboard available. It's four keyboards in one: Speech to Text, Trace (Swype equivalent), Write (like the old Palm PDA's) and Tap (like the default keyboard). Nuance makes the Dragon Speech to Text software, which is recognized as the best on the market. It does an incredible job on speech recognition. I love the way it handles capitalization, punctuation, spelling and word prediction. The Trace keyboard has some different shortcuts from the Swype keyboard, but I would say I like it better now that I'm used to it. Many of you balk at paying for any Apps, but considering how much you use the keyboard and how important it is to efficiency in using your phone, $5 isn't much. Also consider, you probably have already spent over $300 on the phone and other accessories, plus $30/month on data, so what's another $5.
Get Vlingo and FlexT9 and I guarantee you will reach new levels of success with your smart phone.
