DVDs
DVD : Buy it, it's yours. No DRM (well, nothing
good anyway

), and you don't have to worry about a license server shutting down.
Telephone service (POTS)
Don't have one, don't need one. Skype + cellphone.
External hard drives
Versus online services? Yeah, LMK when I can get cheap Internet whose speed and latency rivals my RAID 5 setup.
Oh, and make sure it works without network drivers installed. Hmm...yeah, problem.
Smartphone also-rans
Never had a smartphone, don't need one.
Compact digital cameras
I've got a used Olympus camera that's got more features than I need, but damn the price was right.
Newspaper
<spinning newspaper>
Extra, extra! Newspapers obsolete! This story is already very outdated anyway! Read all about it, unless you already did so online!
CDs
As long as I can get the songs in MP3 or FLAC format, agreed.
If not, I'll buy the CD, then make my own DRM-free files.
New textbooks
Sure, a great plan, except when they switch to version 11 of the textbook, wherein the publisher made several very minor alterations, totally worthy of running a whole new printing.
Inefficient cars
Inefficient homes/appliances
Well, yeah. Inefficiency = long term recurring cost.
