Going with the herd is always going to be easier. Mind you, I remember being on the Samna/Lotus side a while back, (AmiPro/Wordpro/Smartsuite) until a takeover resulted in MS adoption - nobody likes change.
However, my current PC has OEM MS Workssuite, but for my new one, it’ll be OpenOffice, since I don’t need advanced compatibility, I don’t see the need to buy from the behemoth, especially as I’d have to adapt to a new version anyway - oh, and pay again and again every time the MS powers that be dictate it’s time for an upgrade.
Basically, if you know and use MS Office in depth, you will not save, and will not be happy, with any supposed alternative.
Of course, the number of users and companies that excercise any more than the most basic capabilities must be slim compared to the legions who treat Word like Wordpad.
