I think we've had almost all the software we need for years now. Most new software is small variations on existing software. In terms of software that would make you go "oh I really need that" because it's a genuinely novel type of functionality. . . it's hard for me to think what's the most recent software I use that falls into that category. Actually more common is that I use an old, working program but then it stops working for whatever reason (e.g., not compatible with latest upgrades) and then I need to look for "new" software to do the same old thing, which it often doesn't do as well as the old software.
