I had an android that kept doing odd things, so I looked around and saw the Blackberry.
So I bought a 9300 Curve 3G and was straight away impressed that I had 'real' phone keys. The keys are quiet on mine, unless my hearing has gone with my advancing age...
There does seem to be quite a lot of apps....go onto blackberry . com website and look for yourself before you buy to see if there would be enough for you. You have to bear though that I am 57yrs old and find no use for games apps, music apps etc, so although I've noticed quite a few have not looked into them at all.
If you do get one and you like Facebook.....DONT UPDATE TO THE 2.0 VERSION.....loads are having trouble with it. The original version works well and notifications etc can be turned off on it.
If I haven't got things running in the background, my battery gives me a good couple of days or longer.....constantly fiddling with it I get a a day and a half......things running in the background and fiddling a day.
Mine only froze when I had the new update for Facebook on it. That's now deleted and mine doesn't freeze.
I don't use whatapp messenger, but have seen a lot of posts where it runs the battery down. Bear in mind that there are about 4 other messenger apps built in.
Back to being a dumb broard of 57.....yes it's very easy to get used to....found it easer than the android...

Of course I perhaps do less with mine than most on here...they change themes, wallpapers, have games, conduct their business, have apps that I wouldn't dream existed, live their lives on it, etc etc and they will poss give you a better idea of just how mush the phone will actually do...
It does seem that quite a lot of youngsters have got Blackberrys, my neice is getting one, all her mates have got one and at that age they like apps and a phone that will do a lot...
Worth mentioning too that a Blackberry runs on a different data plan that an android and most service providors will chanrge you £5 a month more for the BB data plan.
And last, have you seen the Bold that is being advertised at the mo? Like the Curve but touch screen....could have best of both worlds....although I wouldn't swap my Curve..
If you are someone who likes all the apps going then you MIGHT miss the android. But if you want a brilliant phone that does what is says on the tin and more then the Blackberry is great.
