I would've assumed something like "Ostentatiously" would've been the word; but I've seen "obstreperously" couple of times in this thread now, and had to look it up (it's a new word to me:) - seems to be "noisy and difficult to control", and that gives it a whole different, perhaps more negative slant?
P.S. FWIW, in my limited experience, it is typically the most technologically savvy amongst us that go through incredible effort to discover, purchase, setup, own, operate and integrate retro/Luddite devices in their lives :-)
