Different company but if I ever got serious about doing graphics/photo editing again I might actually prefer a dedicated ~2010-era CS installation on a virtualized legacy box over anything that either Adobe or the rest of the market has to offer today. CS4~6 felt pretty "done". Creative Cloud still sucks.

Surely that's a gaping hole in the market waiting to be filled?

>Maybe with some incompatible save formats

I thought Office used OO-XML, which they released as an open standard (mostly) back in the 2000s. I use it at work (unfortunately) and that seems to be what it still uses, and LibreOffice seems to work fine with it too. I don't think anything's changed here in a long time, but I could be missing something.

>new advertisements

I see nothing wrong here at all. Advertisements in Windows and Office are good things, for MS shareholders: they increase profits. Sure, they make the user experience worse, but who cares about them? If you don't like it, use LibreOffice.

>Office's largest enhancement seems to be Office 365, which offers an inferior and sluggish imitation of the desktop apps running in a web browser.

I'd say this is the biggest enhancement by far. Yeah, it's slower than running in a native app, but it was obviously a direct challenge to Google Docs, which I think came out earlier and popularized the idea of a browser-based office suite. The main advantage of it is not being tied to a single PC (or worse, a Windows PC), and probably more importantly, being able to easily share documents with others, even editing them simultaneously. That really is a killer feature for many.
