I had a Pearl for a little over 6 months, then upgraded to a Curve, no regrets. Like the keyboard much better, bigger screen w/o being that much bigger or heavier...IMO.
I had a pearl 8100 for just over a year and then upgraded to a curve 8320. I really like the larger screen and full keyboard. If you send many emails or texts in a day then you will love the full keyboard. If you want to use it for more of a phone then the pearl will do you just fine.
Had a pearl for about a month or two, then I went and swapped it back in for an 8320, there's not much difference, but if it were me, I'd swap all over again...
Oh ya the only difference between the two is size. Curves got a bigger screen and keyboard, and the pearl's autotext or whatever its caled, is pretty handy, but kind of annoying when you spell words like "see", because it changes to "are". Also"dude" would chang to "fife". That was annoying, but that's it
