This evening, I walked over to my local Barnes & Noble and pre-ordered a Nook. (And felt a bit like a Nook Shnook for doing so. The information booth guys just went onto the B&N Website to order the thing. I could have done that. From home.) Because I ordered today, they said, I'd go onto the waiting list and had a good chance of getting my Nook by, oh, about December 21. (Of this year, thankfully.)
I opted for the Nook, instead of the Kindle, primarily because the Nook purportedly handles pdf files better than the base-model Kindle (which costs the same as the Nook). I foresee using the device mainly for work. Nowadays, all federal district and appellate court documents are served in pdf form; and we scan a lot of the state court filings. I'd rather carry a wafer-thin electronic reader into court than a thick file or a box of 300-page appellate record volumes.
Of course, I'm buying the thing sight unseen, so I'll have to wait and see whether the Nook lives up to its hype; or whether it will just sit in its nook.
