I got it today

I received the Kindle today. They shipped it to the wrong address but I took a long lunch and went home to pick it up. For my trouble I got free shipping. I was so quick to plug it in, breaks are short at the shop. First after getting familiar with the controls (very intuitive) I set to the task of putting the user manuals I have in pdf to the kindle. I used Mobipocket Creator. While it did work, and it is free, the converted file was too small to read, thus far I can't find a zoom on the kindle and had to put it away to go to band practice.

I am home now and am excited to get a couple periodicals and the local paper on this thing and start using it. I miss my RCA ebook and hope to have the same results with this device.

Anyone know how to zoom?? It's been suggested I change text size but these are images not text.
