I almost got a Classic a while ago, but I stuck with my very old Blackberry Bold 9780 because it worked just fine for me and my needs (especially since I had the option to swap out the battery quite easily). But T-Mobile finally notified me sometime ago that my old Bold would no longer work with their new network upgrades. Still, I held out for a while, did some research, and finally went with the Passport SE a month ago.
I was also afraid about the phone being too large -- especially coming from a much smaller phone like the Bold. But I've adapted quite well to the changes, and I confess that I absolutely love the larger keyboard. I can't type one-handed on it (like some others have noted), but that doesn't matter to me since I always typed out with both hands on my Bold anyway. Also, I love the larger screen. It's not as lengthy as most other large smartphones on the market, but it's perfect for me. The metal casing and the speakers are also a plus...and wow, the HUB! Nice. :) Of course, I miss the days of easy-to-swap batteries, but oh well...sadly, that's not the huge trend anymore. Sometimes, I do miss being able to fit my phone very easily into the smaller pockets of my handbag or even a small shirt pocket, but it doesn't bother me as much as I expected it would.
