I couldn't care less about who they are and what they did.
Well, you did ask why everybody hates CUSA - that's basically the majority of the reason. They've been strutting around like King Shit of Shit Mountain for over a year now and acting douchey to anybody who doesn't play along with their delusions of grandeur, and frankly it's soured a
lot of people on them. I myself came into this with no particular beef with the company, but after the past year of watching their behavior (to say nothing of their assorted sycophants) I'm pretty much rooting for massive commercial failure.
I think the HW looks great. With the right SW on it, it could be better.
The hardware really isn't great, though - it's an (at best) mid-range PC board in a "Special Collector's Replica Edition" breadbox case that they're charging $250 for. (Wonder what the production cost on the case is?) I did a price breakdown in another thread, if you want a PC you can get one many times better than the expanded C64x models for less than the price of the
base model. And if you want a C64 case, you can DIY for far less than the cost of their overpriced Franklin Mint crap.
As for the software, they're all talk. They made a lot of noise about running a "custom OS" after using Ubuntu as a stopgap, and now it turns out all they
actually meant was producing a Commodore-skinned Ubuntu variant (as many people here predicted right from the get-go.) They're not going to actually put any effort into the software.
