I am thin and have thin fingers. I couldn't believe how small the keys were and I couldn't type anything accurately not to mention how slow typing was without any type of auto-correction! The keyboard has been the BIGGEST failure of the Pre in MANY reviews.
I can type 70 words per minute on my iPhone 3G and when I first got it it took me about 30 minutes to get to that level of typing!
I think it is quite funny that people rip on the iPhones keyboard and hail the Pre for being so cool and WITH A PHYSICAL KEYBOARD yet somehow Palm managed to make it far inferior to a touch keyboard lol.
