There are probably a lot of long term members here just like you. People who have been here a long time probably followed an evolution similar to mine.
1) Bought one DVD burner in the early 2000s for a couple hundred bucks and kept that burner for a few years.
2) Bought another DVD burner when double layer burners became widely available around 2004 or so.
3) Went crazy in 2006 - 2007 buying DVD drives and media because they were cheap.
4) Bought a Blu-ray burner around 2009.
5) Now, in 2015, use Netflix and Hulu for streaming, burn one DVD/Blu-ray per month if that, and are reminded of how much more money they'd have now if they didn't have a drawer full of media that they overbought and a cabinet full of DVD burners that they overbought.
Like you, I don't keep up with DVD drives very well. In fact, I don't really keep up with optical drives. There's no need to keep up to date on media if your old, dusty drawer is already full of media that is known to work well. There's no need to keep up to date on DVD burners if your old, dusty cabinet is full of them and they all do the job well.
And yes, I have surround sound equipment and am aware of how much better the picture quality and lossless sound quality is on a Blu-ray disc. But it's still a lot more convenient to just search a menu and click a button for Netflix/Hulu than it is to physically look through a non-wordsearchable cabinet, take a movie out, turn on the player, wait for the player to load, 'next' through all the previews, and when the movie is over, put the disc back in the box and file it alphabetically where you got it. For the slight hit in picture and sound quality I'd gladly take the added convenience and reduced clutter space.
It's kind of a drag to read (above) that Lite-On no longer makes Blu-ray burners. If I had to declutter, had money to burn and wanted to consolidate all of my optical drive needs to two drives on one computer, I'd probably use a Pioneer Blu-ray burner to burn BD-R, DVD-R and CD-R, and a Lite-On iHBS112 to burn DVD+R, DVD+R DL (since last I checked Pioneer Blu-ray burners don't do bitsetting), rip CD's/DVD's/Blu-rays and scan CD's/DVD's/Blu-rays.
But, like Dartman, I used to have a lot more toy money so, rather than consolidating, I use a different drive from the bloated, older collection depending on the task. Pioneer BDR-205 for BD-R burning. Lite-On iHES208 for Blu-ray scanning. One of the 5 NEC chipset Pioneer DVD burners for DVD burning. And one of the 5 BenQ DW1640's for CD/DVD scanning.
