Query: Deal breaker: No support for PDFs or other text documents!

I have always loved the idea of an e-book reader, and I've been waiting for someone to get it right. When I read that Kindle was announced and had wonderful features like- wireless support- SD card support- PC sync- an online storeI had my credit card ready. But then I realized that it does not support PDFs or other text file formats.What am I going to do with the hundreds of e-books I already own?What if I buy e-books from other vendors and want to read them on this reader?In an age where everyone is moving towards providing an open platform to content creators and consumers, here is a device that will tether me to using its service. And that, for me, is a deal breaker.
