Query: I feel so sorry for myself with kindle

oh, man. kindle seems to be great on ads, but suck in real. It is useless to me. Now it supports PDF file, but It doesnt work at all. if I have to send pdf file to somewhere, I dont know what would be with my stuff. I had better buy a small notebook (about $200) which supports most types of file. I just want to it put in the trash. It costs my time n energy for this stuff.Im sorry, but this is absolutely true.
