About saving, I say you should be able to save scum however much you want, with the possible exception of special very hard difficulty settings, and saving and loading shouldn't be restricted unless there's a good technical reason why the game can't properly save (or load) that particular state. Games can track it if they want to add some pressure (I think Deus Ex tracked number of saves and Blade of Darkness gave a rating according to average saves per level), but still let it be the player's choice, whether to care for those counters/ratings at all, what if any limits to impose on themselves, and where to use those limited saves if they do want to limit them.
As for the original question, yeah, what's been said, controls and UI (I have a mouse and a keyboard, let me make proper use of them!), saving restrictions, QTEs... Regarding the graphical issues mentioned, I'd list the complaint as reduced options, and that isn't just limited to graphics, so let people adjust settings according to both preference and system, taking the game from running on the least powerful it can manage (and/or as un-"flashy" as it can be for people who for some reason prefer that) to showing off all it has if the rig handles it and the player desires it. Then, of course, reduced size, length and complexity, but how much that is due to consolitis and how much due to the developers just wanting to make things easier, or likely even more so publishers wanting to get releases out ever faster, not sure.
