Well there was the same question asked, but its over a year ago. I recently bought the Acer A100 tablet with dualcore arm cpu in hope to view some PDF ebooks smoothly (able to zoom and pan smoothly). It proved incapable with Adobe Reader and Aldiko. Infact, it was no faster than my single core phone. It seems that its the software side that's the missing link. Sorry this might be a bit off topic since I'm going into the hardware too, but is there any android app or tablet ($400 or less) at all that can view pdf smoothly or at least reasonably well? I'm also looking at the HP Touchpad if its possible. Nook? Just want to avoid paying Apple and Microsoft though.
