I purchased my Sprint Hero on January 23 and also purchased a ZAGG screen protector, both from Best Buy. The best buy rep installed the screen protector so I had not used my hero without it. With the screen protector, everything worked but seemed a little "tacky" when sliding my finger across it as well as always having smudges. I finally decided just the other day to remove the screen protector after watching some scratch resistant video's on youtube. WOW! Now the screen is so much clearer and when I slide my finger across it, it feels like silk. Even texting is much better. And as far as smudges, the screen is very smudge/fingerprint resistant and easily wipes clean with a soft cloth. So, if you have a screen protector, just wanted to let you know that the hero IMO, is much brighter and easier to use without it. I don't plan to use another one. From what I've seen, the screen is very durable and scratch resistant.
