Re: I'm a big fan of WPS Office
Just to enlarge on my LibreOffice isn't stable enough for business comment. About 8 months ago, LO trashed my entire Ltd company books through a bug which silently corrupted formulas when saving to .xls format. Eventually my accountants had to rebuild the books from scratch. The whole experience was so blood pressurey that I afterwards swapped to OO and haven't had a problem since. IMO, LibreOffice is unstable. Even the "stable release" branch changes too much, too often, and the devs prefer working on enhancements to fixing bugs. Not appropriate for a serious business application. Stability might be boring, but in business, it is beautiful.
Reading about the bug over at the LO project I found it had been outstanding for some time, through several releases, and the maintainers' attitude was laid back, if not irresponsible. The main comment I remember was them saying "...well not all spreadsheets are critical... so corrupted data isn't really important". Well that's allright then. Only, I hope the next aeroplane you get on wasn't made with parts ordered with a LibreOffice spreadsheet. Hope I don't go to prison for not keeping proper books on my Ltd company. Hope my prison release date is not stored in LibreOffice, hope your pension is not calculated with LO, etc. etc. OK sorry about the rambling rant.
