I long ago came the the conclusion that
acquiring books and
reading them were two separate and distinct pleasures, so I needn't feel guilty about getting six books and having time to read two.
Yes, it's a sophistry, but it works for me.
I have about 3,500 ebooks on my PDA, and likely as many paper books, though I haven't counted heads lately (and some of the pbooks are in off site storage and not easily countable.)
There are an assortment of ebook sites I trawl daily, including Munseys, ManyBooks, and PG, looking for things of interest. The Ebooks folder on one of my secondary drives is currently about 11GB, with 49,000+ files. (That does not mean 49,000 book - many are HTML with more than one file per book.)
The nice thing about ebooks is that you don't have to call the paramedics if my unread ebook stack topples over on me.
