I got one. I got an Apple iPad. Many years ago I got my first iPod and just the other year I got the iPhone. I am happy about my purchase so far. With thousands of free books (I already downloaded 49 of them) there's plenty of reading at my fingertips. I plan to replace my physical book classics with digital editions to free up space in my office.
I do not plan to purchase a 3G edition since the Wi-Fi only iPad is good enough for me to use and develop with.
UPDATE: I now have over 700 e-books. I have only purchased two: The Hobbit, and Lord of the Rings.
