Keeping my iPod Touch 4G
I have an iPod Touch 4G and I will definitely keep it even after I get an iPad 2. I carry the Touch with me constantly. If I'm waiting somewhere, I can listen to music, watch video, or play games. I agree that PDFs and ebooks are challenging to read on the small screen and I'm looking forward to switching most of my reading to the bigger iPad screen. But the Touch has it's place and I will still use it to discreetly check my emails during meetings, look something up while I'm talking to a colleague, and check the news when I'm in the bathroom 😉.
