BlackBerry here! My first BlackBerry was AWFUL but it got replaced for free with insurance. The one I have now is about two years old, I think, and fine. I'm not really so good with the phones and I am definitely awful with touch screens. The BlackBerry is a corporate holdover and still, i think, probably the easiest thing to use for e-mail and almost nothing else. I pretty much only use it for e-mail (and phone and texting), so it's fine for me.
I don't even know if they make BlackBerrys without touch screens anymore. If not I don't know what I'll do when this one goes. I still mourn the loss of my LG, the greatest little phone ever made. Did everything right, good size and weight, and lasted forever until the charger spikes got knocked out of line.
