They're quite usable, certainly beating MS Works at this time. They're also arguably better code somehow (e.g. startup time is very low, and unlike in MS Office I've never seen the UI lock up on a big document, everything is very responsive and very fast). Opened very complicated excel docs of mine and it looked fine, and frankly it was more enjoyable than MS Office to work with. Saving it and opening back in Excel was also just fine.

They've also eliminated what I use Google docs for: paste some shit into docs and save as pdf, it's much, much faster at that than Google docs.

I've written a script that deploys the wasm versions on kubernetes and makes an index page to allow to start them quickly so you can try. There's an update script that runs regularly too.

They update like crazy too.
