Nice little device. I'm considering getting the S18, but I'll wait for the reviews first. The size doesn't bother me, my cell phone is the tiny Motorola Flipout with a 2.8" screen, but I love it. I need to upgrade to an iphone in December and I'm going to miss the Filpout.
I think typing works better as the device gets smaller. I have a NOVO7 Paladin and I hate typing on that. It's too hard to hold with both hands and type with your thumbs. If everything works on it, the S18 could be perfect for me.
