One of the biggest pitfalls that the xoom had for me was the searching speed on PDF. I use PDF's almost 100% of the time on my tablet since I have my text books on pdf.When I need to find a question such as "13.4-5" it would start at page 1 and search, page 2 search and it was easily a second/page(1000 page text books). I did this with the same book on my iphone 4 and it gave me instant hits. I tried nearly every free pdf viewer on android and they all searched this slowly, so I bought repligo(one of the big time pdf apps; same story. So it's not about seeing a bunch of data at once, it's about accessing data quickly and I think that the idevices are better that that.
