It's getting there and more than good enough already
When talking about something being 'good enough', it's easy to infer that it's good enough but only just, or it's not excelling at anything and so forth. I have been using Microsoft Office since 1994, and Word since v5.1 on a Mac Plus. As such I consider myself a veteran user who used to do a lot of Access/VBA development, and I use Word and Excel extensively still at work; and occasionally I knock up a presentation in PowerPoint.
In the past six months I have switched to using both Ubuntu and OpenOffice.org exclusively at home; for what it is worth I am not a Microsoft basher, nor do I think that transposing the 's' for a '$' is funny or cool. I like Windows XP (not so fond on Vista but that's preference) and use it daily at work, and for the most part it works well. Outlook 2003 being an essential piece of kit though I admit I probably don't use 10% of its capability. I use Ubuntu at home because it's better for my needs, not because it is better (or worse) -- it's an alternative that has come about because of freedom of choice; not dictation.
Apart from one annoyance (Word documents with tables within tables do not import correctly) I can honestly say that OpenOffice.org does everything I need, and again probably more than I need. I am most of all impressed with Writer which ***for my purposes*** (as a writer) with correctly formatted documents using styles blows Word out of the water. It doesn't annoy me to death with style annoyances, quirks when I create documents using complex numbered lists and more besides. I also think OpenOffice.org the typography is better than Word; but that is subjective. Let's face it, TeX and InDesign (which might use the TeX engine, not sure) blow each out of the water.
What this shows is preference, the ability to have a choice.
People should be able to find comfort with what they prefer using, the tool that suits their needs best. If that is Microsoft Office, then good for you, I hold no issue with that. If it's OpenOffice.org, good for you too but please don't ridicule those who use MS Office as it's stupid. The same applies to WordPerfect, AbiWord, KOffice etc. users.
The issue is that people should at least be aware that there are alternatives to Microsoft Office that they may or may not find more comfort with. If there was only once choice, the applications would stagnate, as would innovation and our productivity. Secondly: it would be nice if they played ball together nicely. For this reason, high profile products like Google Pack are important for raising awareness that users can have a choice if they choose.
That's what I believe made computing fun: the fact we could craft our systems with the applications and tools of our choice, be that Windows, Linux, Mac OS X, hell even if you want Amiga Workbench (!)--and without variety, I believe computing would be a much duller, utilitarian hobby, interest and activity.
