I spent most of yesterday configuring my wife's new iPad. I've had mine for a few months, so I was pretty familiar with the device. It still took most of the day to get all of the applications she wanted, to log into everything for the first time, and to get everything customized to her liking.
When registering, Apple asked what was the primary reason for purchasing the device. We selected "eReader". It really was the best choice though I would have laughed at this suggestion just a few years ago. Being hardcore bibliophiles (who can appreciate an exquisitely crafted volume) and owners of first generation Kindle devices, I didn't really see much need in using the iPad as a reading device. But, that is what I do. Everyday. All the time. I would say I easily do ninety-five percent of my reading on the iPad now (and I read quite a bit).
Multiple eReading apps have arisen (iBooks, Kindle, Nook, Google Books, Kobo, Stanza,...) to give plenty of options. Each has its own strengths and weaknesses, so it really comes down to which features are important to you. I do most of my reading of late using Kobo.
Of course the devices do many other things too. Today we will reap the fruits of yesterday's configuration. We can sit down and have some fun with the devices. And get some reading done too.
