Yup, I am not saying SDRs are bad. They are good in some respect, and there are demands for them too I suppose.
But, it depends what one is up to. I mean, to start with, I don't listen to Utils on SW, and I never run more than one radio at one time. So running so many different bands and freq, even with one SDR is not for me. I mostly listen to the SW broadcasting stations and the Amateur Ham bands. I don't need the fancy waterfall displays on my PC screen for that.
Also I like being independent from Software updates and bug fixes for the SDRs. i had enough pain and trouble doing the updates when I was using the dreaded WINDOWS 3, 4,7, and 10 in the past. They slows your PC down, and always something didn't work after the updates. I used to feel my PCs were under the ransom of the updates.
And I like the idea, if something goes wrong with my radio, I would open it up, and having a good look at it trying to fix or repair it myself. I am currently working on repairing and restoring 3-4 old radios.
That is not possible with SDRs. It is a black box with tiny PCB with tiny SMDs driven by the software, which is also blackbox. There is no option for mods, or repairs if needed. You are dictated by the SDR company's control. All you are allowed to do is to set it up, watch the waterfall display of the spectrum, and listen to it, and no more. But you could do it on the Apps. I don't think you even need to attach the antenna, but just use your broad band internet connection, and hear all the Utils and everything on the AIR, if wanted to, all for FREE of charge.
So why did you even pay 50$ for a SDR and attach HF or VHF/UHF antenna to it, and hook it up on your PC?
I think it is still useful for the people who don't want fuss with mods, and repairs, and just get on with listening the band. And I am planning to get one eventually when I see a good deal on it.
It is just different interests, not necessarily one is better than the other. For me, tuning around without any knowledge what I will listen today on the band, improving the set by replacing the parts, and trying repairing it by myself when they go wrong, and the way they sound mellow analogue rather than dry hard digital, and the way the set looks, ... they are all part of the fun

So, it is not that simple and it is not correct to judge, that I bought the R71E just purely for nostalgic reason only.
