I hate my blackberry.
'Tis awful. The worst smartphone I've ever used. I can't wait to replace it.
Actually, the Blackberry Peral is the BEST phone, smart or dumb, that I've ever owned. Except for an old analog Erickson (the first handheld phone I had, after the days of the bag phone) the Blackberry is the first phone I've owned that was still working when I replaced it. That feature is allowing me to disconnect my land line, since I now have a back up phone if I (or the cows) break my main one, and as I'm on 24 hour call at work every other weekend, that is an indispensible element.
I use a database program called HanDBase
http://www.ddhsoftware.com/ on my Palm TX, A LOT, and the TX is fading now. They make a Blackberry version of HanDBase, but it is pretty feature lean compared to the Palm OS version, and I read some troubeling things about HanDBase & Blackberry, so I downloaded a trial version to try on the Peral - one word:
SLOW, to the point I considered it unuseable. The programmers say it is because of RIM's java based OS, just not conducive to these types of programs, though they hope to find a way to accelerate it's performance in a future update. I tried another database type program I use often, Splash Shopper, and likewise, it ran much slower on the Blackberry than it did on the Palm TX. As a communication device and a sturdy piece of hardware though, I think the Blackberry is totally awsome. If it weren't for my need for HanDBase, I would have defiently gotten the Curve with the track pad. The Android version of HanDBase is still in development and won't be out until summer, and I had no idea what features it would have, or how it would perform. On the Pre I can run HanDBase, and some other fav Palm OS software, like Iambic's Agendus PIM program, through Classic, and that is working great. The old Palm OS programs on Classic will also wifi hotsynch with my computer (my gripe with both WebOS and Android, and their stupid "cloud" things). The Blackberrys still USB cable hotsynch with a computer - I like that

. I had avoided Win Mobile up to this point, so consider it best not to start now.
As a Sprint prefered customer, I'll be eligible for an upgrade in 12 months, so I hope there are better offerings: Maybe Web OS will be both more mature, and available on better hardware. There is net talk (or wishful thinking) that with Palm going broke, and RIM loosing market share, having Web OS on Blackberry hardware, with RIM's communication savey, we migh see a truly awsome device. Likewise, maybe Android will grow up and decide it can be a functional tool to working people, and not just a toy with a zillion useless apis. There is even speculaton that the I-Phone will be at Sprint by the end of the year. AT&T's coverage sucks where I live, so that wasn't even an option at this time, but everybody I know who has an I-Phone loves it, when they can get a signal.
