This app has potential. Right now it is a bit laggy to make for a good user experience. Most importantly, the app does not (as far as I can tell) offer the functionality of choosing a variety of text sizes except via using Apples two finger zoom gesture. This is totally unacceptable as it then pushes most of the page off the screen forcing you to pan like a mad person looking for content. This app needs to offer the option of larger text sizes and it needs to do this while reformatting the page so that panning is unnecessary. I am a teacher. Some of my students with only modest visual impairment would not be able to comfortably read the books as presented. I may be wrong, but is looks like the original paper textbook is made to fit the iPad screen...which is smaller than most textbooks. This forces the text to be smaller. Also, and maybe I was just unlucky, but the textbook I use in my physics classes was also not available. This, despite being the most popular physics textbook on the market today.

Great all around app. The fact that I can download any free PDF makes it worth a download, and will be very useful next semester

I think this would be one of the most popular apps for college students to use if it was more like iBooks reading style. Such as the page turning and dictionary function.

I am really liking the functionality of this app. The highlighting functionality is a bit buggy (hard to edit a selection) and I'd like to be able to page left/right by tapping the sides of the screen.I haven't yet added books, but I did add a PDF, an action I'd like to be able to do through iTunes. The book search and purchase experience seems quite well-thought out. Finally I'd like to be able to remove the sample book section that they've added since I don't need instructions once I've read them.All in all, I'm liking it and can't wait for the next few updates.

This app has a great potential but is way to laggy and slow on my iPad 2 with no background apps.

This is an indication of beginning of new era in which students will finally be able to lower the weight off their shoulders and would be carrying light weight iPad instead of bulky bunch of books.I love the highlight features of this app. It has built in dictionary that comes really handy. If you want elaborated definition,you can be directed to Safari browser and by double tapping you can come right back in app which is another stellar feature.But I didn't find even one book for my purpose. For couple of searches,it said "make a request" but rest of them ware not even found in it's database which indicates it has very few books at this time so it won't solve the purpose of serious study.Now it depends on the app owner, if they are really serious about making their presence well felt,then the first thing they need to do is increase the library of books.

Being able to carry 4 or 5 textbooks on my iPad would be insanely helpful. The app does crash a couple of times and the book shop is still being developed. Keep working on this app! It has a lot of potential!

This app seems to have great potential such sticky notes, highlighting, etc. However, very limited selection of books, not clear on how much a book cost as the price list makes no sense ($4.99 for one book, $119 for three books?), can't seem to make text size different. I assume the sticky notes etc, will transfer over when the app upgrades, but not sure about that. The books I looked at did not have any additional features such as video, animations, interactive diagrams: would have been nice.
