What's the use case for LO anyway? If you need power and compatibility, LO is still gimpy and not rock solid compatible so you still need Office. If you don't need power and compatibility, Google Docs can do pretty much everything LO can with less bulk and nice Google integration.
So LO is better for... users who need more power than Docs but less than Office who don't care about Excel compatibility, and people who don't have internet connections? That seems like a pretty small market.
1. Free, and more importantly, free updates.
2. What features are you missing?
3. Define "gimpy"
I've been using Open/LibreOffice for about eight years. It works for me. I have seen compatibility issues with it, though they haven't happened for me personally. A customer had some Works documents and LO's support for that wasn't good to begin with, but it seems pretty solid now. I remember when OO/LO's support for MSO2007 document formats was very shaky, but it has much improved. I can't remember the last time I saw an MSO document compatibility issue, but I'm not going to claim that they don't exist.
I would say my use of WP and spreadsheets uses maybe 10% more of the features available in an office package than say the average user does. I've used every MSO version on and off over the years since mainly using LO. Each has its foibles from what I've seen.
I find it funny how every time MSO compatibility or feature set is mentioned, some vague reference is made to say how LO is lacking, like 'copy paste' earlier... the last multitude of times I used copy and paste in LO, it worked.
PS - I'm not saying that LO is for everyone, I'm sure that people use features that aren't in LO or not properly supported by LO, but if you're going to criticise it at least come up with a case where it didn't work for you instead of making sweeping generalisations in the hope that no-one challenges it.
Regarding MSO2k13 - Apart from a UI change in 2k7, I couldn't name a single real improvement since probably MSO2k, except for OS version compatibility improvements which is pretty much a given if we're talking about Windows. MSO could basically do what I needed it to do since say Office 4.3 or 97. I really wonder how many people here can honestly say that last statement doesn't apply to them as well.
I hate MSO2k13's attempt at making text appear "smoothly" though.
