What is the best smart phone for medical software?

My wife is a third year medical student looking for a Smartphone to put medical software on. We have heard that blackberry is the best smart phone but we鈥檝e also heard that most of the medical software is Palm or Windows Mobile based. Are there any medical professionals who can recommend a particular smart phone platform?|||A lot of people in the medical field I seen you the Blackberry I or Blackberry II so i would go for one of them. Blackberry's can and will talk to you if you have the settings on right and has GPS.
