How long before I succumb to e-books?

Too many CDs and too much convenience from iTunes / iPod have virtually halted my purchasing of physical CDs.  I now buy at least as much music in purely digital form as I do on CD - probably more.

I stopped buying printed newspapers in about 1994, when we moved to Holland.  These days I read a selection online, including on my iPhone - it's perfectly possible to read a long piece that way.  However, I do still get printed copies of the Economist, Wired magazine (US and UK) and Prospect magazine.  I've always taken weeklies and monthlies since I was a kid, and I like having the physical paper handy.

I take a load of photos but most of them exist only in digital form.  A couple of years ago I did take the plunge and have 500 or so printed up, but we look at them less often than the digital versions.  In the next week or so I'll be selecting, processing and sending off a dozen or so photos to make big prints for an exhibition - but they're the exception.

I work entirely paperless.  The only things I ever print out are for the accountants.  For the rest, it's all digital. 

I have bookshelves full of books, many of which I'll probably never get round to reading.  Yet I still can't resist buying titles that catch my eye, even though many will only ever gather dust.  In some respects it would make more sense to get them on an e-reader,  Yet at the moment, that feels like one screen too far.

I'm sure that if I actualy took the plunge and got an e-reader, I would be hooked.  However, looking at the move from this side of the decision I feel sad about it. Books are the last hold-out of analog content in my life.
