Backwards compatibility was taken away, in conjunction with a price drop because eliminating those chips significantly lowered the cost to build the machine. I'm more than happy to have saved $100 on my PS3 to lose that.
Cross-game chat (which is what's really being asked for; plenty of games have implemented their own in-game chat), while trivial from a technical perspective, has the issue of Sony not being able to increase the memory or CPU footprint of the OS while a game is running, lest they break one or more of the thousands of existing games. So if they added that, they'd have to find something to carve out. Theoretically I suppose they could build more RAM/a faster CPU into the newer machines, but only those would be able to support chat.
So between someone with no experience but a degree, and someone with 5+ years experience (at the same company) and no degree, you'd still opt for the degree-bearer?
I would have thought the work experience would show that they can do #1 and #2, and probably #3 as well...
You need to go back and play the original X-wing and TIE Fighter. (Not the Windows 95 ports, the DOS versions.)
Also, possibly Wing Commander 1 & 2 (scored by The Fat Man). But I'm embarrassed to say that I haven't played them yet, despite owning the GOG rereleases.
From the publisher's perspective, the ebook's costs are hardly "negligible", as the retailer gets to skim 30% off the top. Less than a print book (the retailer gets 40-50%), but a decent-sized chunk of change all the same.
