I've had one Samsung, and it was good but its battery wasn't what it should have been. If you get the Samsung and buy it from a retailer, sometimes they'll throw in an extra battery as backup if you ask for it.

My last two cell phones have been Motorolas. I ended up getting a new one just three hours ago because my previous one fell in the pool earlier today and didn't survive that experience. The new one's called a Motorola RAZR. Don't know how I'll like it since it's still brand new to me. Right now, it intimidates me.
