"My big concerns are support and training" If you find an awkward corner case in any piece of software then you will find support rather lacking from the vendor. I use LO myself: I'm a business owner and can use what I damn well like! I don't force anyone else to use LO but we are a MS tin partner or something so get our tricks err drugs err software a bit cheaper. Training: I was a trainer back in the day and it's all about concepts and not the implementation. I've used Word from v1 to date and 2.0 was a sweet spot in terms of functionality and performance (2 floppies worth of code but could do quite a lot of decent WP and rudimentary DTP stuff eg hanging indents, decimal tabstops and text/image frames with text flow. Modern LO Writer has a turtle implementation in it, coz reasons. Nowadays I struggle a bit to find things in the ribbons. Super Calc, Lotus 1-2-3, Excel and LO Calc all do the same thing in the end to a greater or lesser extent. I wrote a Finite Capacity Planner (yes: Finite) in Excel for a factory around 1995. I'd have to rewrite my functions in Python or whatever but it would run in LO quite happily. Another anecdote: My wife is not IT minded in any way as such and has worked as a classroom assistant in schools catering for special needs and adult support services etc for several decades. She has had various IT offerings foisted on her from Acorn Axxx machines to PCs running Win 9x etc. At home she used to have Windows on her laptop but I eventually had enough at Win 7 when yet another graphics "driver" update needed a good six hours on the operating table to fix. She now runs Arch (actually!) and doesn't care. It just has to work. She also uses LO, which seems to work OK and isn't the oddest office suite she's been forced to use. Don't overthink it. LO Writer and Calc are extremely capable apps and Base looks like a pretty good effort too when I've used it and you get all the rest of it but I tend to avoid Presentation type apps (such as "Poor Point") If you are capable of running a start up then LO will work fine. If some of your staff are incapable of any flexibility - I'd start to reconsider my choice of staff. A startup is all about being flexible and seeing opportunity and so on. If any modern IT user is "incapable" of getting on with LO then I'd question their ability to work in a startup environment.
