I've had a Kobo Touch for about 8 months now, absolutely love it. I have one DRM book downloaded through the Kobo book store and the rest of them were side loaded through Calibre. No problems, nice and smooth. The device doesn't require Calibre for side-loading either as you can just drag the epub to the mounted device. Loading and using your own fonts is also a nice feature. As for PDFs, if they are smaller page sizes it's pretty good, but the zooming and panning functions are kind of a pain--mainly because of e-ink, but partially due to UI. I've only had one issue with the Kobo Touch when I had to reload my books, as for some reason the database became corrupted.
