Excellent service Excellent service. Books are easy to select. Ordering process if flawless. Actually ordering a book means some waiting time because of environment conscious print-on-demand system. But this is perfectly OK. If you are in a hurry: aim for the e-books.

Convenient Easy to use, and it was good to be able to download the various ebook formats in one place. I wish though there wasn't a time limit (due to various device issues, accidents, etc) on retrieving the books if you have paid for them, but I have no good or neat recommendation for handling this situation.

Avoid vendor lock-in with Apress PDF books Apress is the best place to buy computer programming ebooks because they are available in PDF format that can be viewed on any device. I recently wanted to clear my purchase history on Amazon and my only option was to delete my Amazon account and make a new one. I lost several books in the process. Now I try to buy only PDF books exclusively. Apress also has a wide selection of books on almost any programming topic. I have found them to be very informative.

Customer oriented site Customer oriented site, with sofisticate search engine to locate the right books you are looking for. For each book a concise introduction introduce the topics, so that you get an good idea about the book's content. Great.

Wide selection of technical titles I've been an Apress customer for almost ten years and have noticed how it has steadily gotten better with time. Apress Access, in particular, provides unprecedented access to digital e-books related to very specific programming-related topics. The company constantly pushes out relevant and updated material that keeps up with the times. One of the nicest features is that Apress gives user the option to download books in EPUB and PDF formats. Both support the majority of e-reading devices. Sadly, the company stopped supporting MOBI formats for Amazon devices a few years ago. That means customers have to perform an additional conversion step if they want to use devices that only read MOBI files.
