Just for the sake of argument -- We tell software startups to get their MVP out as fast as possible in order gain feedback and improve the product... yet we smack down hardware vendors who have done exactly that?
Well, something half baked is not always an MVP. Sometimes it's just half baked and should not have been presented in the first place.
Not to mention, software startups products don't cost hundrends of dollars to buy and test. In fact, usually they are free. So, pushing a half-arsed hardware to buyers? Not so wise.
The original iPod was a MVP launch ("no wireless, less space than a nomad, etc"). It took it several years to get large disks, video, wi-fi sync, etc.
Google Glasses? An ill-thought, hastily implemented product, merely combining non-optimally a few pieces of stuff you already have (voice recognition, eye displays, small video cameras etc) as "innovation theatre".
