Hey everyone, I'm brand new to the iPad ecosystem and have been disappointed so far. I had a heck of a time finding a decent office suite and PDF reader. I settled on Quickoffice and Goodreader. Problem is, both programs run ridiculously slowly on my iPad. Goodreader is very, very choppy when scrolling around PDF files--basically unusable by my standards. Quickoffice lags when I type anything, so it's also pretty much unusable since I make tons of errors. Is this a problem with my iPad? A problem with Retina Display incompatibility? Or common issues with these apps?
