Come off it mate - like you I'm a big fan of PT and use it daily for a living.
But let's be honest for a second - Digi have purposefully cripple LE in a number of places specifically so that people want to upgrade to HD. And whilst the ADC might not be an issue for you - it is for me. Even basic plugs like (believe it or not) Smack and things from McDSP which I own cause problems - particularly when you're parallel compressing, or have it inserted on OHs but not your snare and you start getting phase issues.
Yes yes yes you can buss things around and stick short delays on them etc but as it is I struggle with only 32 busses nevermind having to make more to get over some stupid oversight from Digi.
As I said - there are work arounds, but it's really really fucking lame that a company like Digi should do this. Putting ADC in to LE would NOT curb the demand for HD, regardless. YES it would require a complete re-write but perhaps they'd be better spending the time doing that than pointlessly changing the GUI and moving buttons about!!
