I moved from the A630 to the MDA.  I send 1300 - 1700 text messages a month.  This phone is great for message heavy users like myself.  I have not had the trouble with the battery life that the other reviewers are talking about.  I use the internet, the phone, the real player and send tons of text messages every day.  I never have to charge the battery during the day.  I don't use the handset much.  1. because I don't make that many phone calls and 2. because I don't use the handset.  I use the bluetooth earpiece for 99% of my calls.  I've got the Cardo Scala 500 earpiece and the Cardo Scala Rider (motorcycle earpiece).  They both work great with this phone.
