I've seen a lot of discussion on threads here--even participated in a few--about the viability of the CRT market, its size compared to the LCD/DLP/etc. market, its longevity, blah, blah, blah. However, the fact remains that ANY market only matters to ME if I'm interested in it.
When my kids were young and at home, I had minimal interest in the upgrading of my audio or video systems, because, as others have mentioned, there were other priorities and realities to deal with. As time passes, kids grow, opportunities present themselves, then things change.
Nothing is future proof. Anyone who believes that something is future proof is... (tact prevents me from saying). I use reliability, quality, value, and feature set to help make decisions, but not the futile search for semi-permanence.
My first mainstream computer was a 386 running Windows 3.1. Everyone said get a Windows machine because that was future proof. It's what everybody, including business used. So I got the darn worthless piece of crap. Can you tell how much I liked it? That's the last time I let consumer market or business market preferences drive my decisions.
I've been happy with Macs for 12 years now. (Nobody uses Macs. They're going out of business. They're not real computers. There's no software.) I drive a Hyundai Sonata, perfect in the first 40,000 miles. (Korean cars are junk. The quality is bad. You can't get parts. Even their own dealers don't want to sell them. Only poor or ignorant people drive them. They're going to fail in the American market.) I listen to JBL Performance Series speakers. (JBL is a consumer brand. No audiophile would use them. Their glory days are over. Harman International ruins everything it touches. JBL is a dinosaur on its way to extinction.) And I have a 7" Seleco CRT. (CRTs are dead. CRTs are too big and heavy. CRTs are old tech. Seleco is unsupported and unknown in the US; you'll never get service or parts. CRTs are too hard to set up and maintain. You'll never be happy with 7" tubes.)
Well I could go on (and I have!), but my point is you're happiest when you get what you want, not when you get what someone else wants you to get. I create my own market and search for a product to fill my one person demand. If the product doesn't exist, then I have to change my preferences, don't I? But I don't need anyone telling me that my preferences are wrong or that I'm buying in the wrong market. Neither do any of us.
Buy what makes you happy or what fits your current reality without apology. You (and your family, if you have one) are the only one(s) that has(ve) to live with it. CRT, LCD, DLP, plasma screen, whatever, buy what makes you happiest and be...HAPPY.
