It wasn’t by choice, entirely.
My positively horrible Blackjack broke just one month after its warranty expired. The charge port had come lose, and none of my charge cables could get the phone to even hold a charge, unless I physically held the charger against the phone for the entire process — not an option. Particularly since I was heading on vacation to Hawaii that day for a week.
So, prompted by all the other horrible Windows Mobile-based problems I’ve encountered on that phone, I decided to break with that platform completely and give Blackberry a try. Blackberry’s reputation is just too good to pass up anymore.
