I feel the same way for the most part for myself. The only console I still have is my Xbox 360 so that I can play Orta from time to time. I have sold everything else off as I have digital copies on the PC of all my old favorite games. I have always been more of a PC gamer anyway, so disks have always been optional. The only game disks for PC I still have are for Half Life 2, Unreal, and Ultimate Doom. I used to collect comics but have sold them all off. I still have my old music CD's in a box downstairs. I used to only buy the CD and rip it, but now with Amazon, I just purchase albums digitally. I do still download and backup quite a range of files which I will talk about down the page.
The few physical items I do still collect keep are books. I just don't think I will every part with my book collection. Every book I really enjoy I purchase and store for later reading. Quite a lot of the books I own I have read multiple times. I don't really trust digital stores to stick around forever, so I would rather have the physical copies. The only other possessions I own are my telescope and lenses, my laptop and accessories, and furniture.
Unfortunately my minimalism doesn't mean less clutter as I am married with two daughters. We have toys everywhere, my wife is a bit of a hoarder (or really just doesn't like throwing paper away). I do my best to clear out my families items that aren't in use, but I have had to let go when it comes to have stuff just laying around. I have hopes this will get better as my kids get older, but I am not holding my breath.
Now I do have quite the digital collection. I buy almost all of my games exclusively from GOG.com and I have the install files updated and backed up on my desktop PC downstairs used as a file server (with RAID mirroring) along with my travel copy of the archive via a portable HD. Aside from GOG games, I have ripped all of my music, quite a few of my DVD/Blu-Rays, lots of PDF books and comics bought from Humblebundle or aquired via other means, emulators for all the Sega systems, some for Ninty systems, audio books, all my programming files and school files, user manuals for stuff around the house so I can throw the paper copies into the recycling, and a few other categories of files including our family pics, etc. My digital archive is about 2TB in size (mostly because of movie rips). Without the movie rips I would say I have about 1TB.
So in essence, I would say I like the minimalist lifestyle, but I still like to own/have fun stuff to do. If I was single, I probably would get away with a bed, table to eat at, a sofa for people to sit, a few large book shelves, and a PC desk with a monitor to be used as a TV for streaming video. The reality with kids though is completely different!
