Disclaimer: It's kinda hard to search for this question, as Google would give me mostly iOS programming topics.
I'm planning on buying an iPad2 and I wonder if other programmers have found it to be a practical, and hopefully, better replacement for books.
Despite the availability of online tutorials I have found the times I have learned best and made the most progress is when I forced myself to sit down and read through manuals, from start to finish.
I guess the crux of my question is: as a developer, have you been able to use an iPad for reading programming books in a way that it is more convenient than Cmd/Alt-Tabbing between a PDF viewer and other apps on your computer?
Also, does the iPad PDF viewer remember the last viewed page of every PDF file? (Like Skim does on Mac OS)
