Personally I hate the NeXT logo. I've always thought about just how awful I think it looks every time I see it. This is the first time I've got the sense that people genuinely love the logo. Very interesting!
Note too, that most logos in use today are tweaked versions of their former designs, even if the designer was such a design icon as Lowry (e.g. Shell and BP logos). For example Apple's rainbow logo.
I think it looks as if designed by a techie.
I guess all these things add up to 'cool logo by a millionaire for a billionaire' in some peoples minds, but to me it just seems like cat barf. Literally, as in .. something that was just spit up, with chunks of undigested stuff in it.
