I use LO for 99% of my stuff now. Have some stuff can't yet port from Excel. And while I love open source and LO in particular, have been a bit disappointed at the instability. Shit crashes if you make some mistake. I mean close down, lose your unsaved work kind of crash. Like if you try to resize a column wrong. And CPU 100% hangs are pretty frequent. The worst is when researching all these problems, info is scarce compared to MS. Most "help" comes from this one kinda asshole German guy with a pluto the dog avatar. If I was an IT director with any kind of budget, I would really think twice before porting an organization to LO. MS on Wine is more stable than LO for me and rarely crashes and never hit infinite 100% CPU thing. But performance is much slower on MS than LO on Linux.
