OK, so about 3 weeks ago, I had an issue with my iPad 2. Took it into the Apple store and they gave me a replacement. The replacement was in a brown box so I am assuming it was a refurbished one. Over the next few weeks I noticed that the screen became dirty much more frequently. On average I use to clean the screen about once a week on the old iPad. It was just finger prints for the most part and nothing that was noticeable to the touch. Lately the new iPad has really gotten dirty and there is a residue of grime. I know this sounds like I have dirty hands but I don't. I'm pretty OCD about washing my hands and I usually wash them about 10-15 times per day, maybe even more. It's so bad that I have to clean the screen every day. Am I nuts or is there something wrong with my iPad screen?
