I used OpenOffice before. But when my kids started to complain that when they do their homeworks, they cannot do it quickly because the school trained them to use Word and Powerpoint, I had to switch back.

I guess P350 a month for a software isn't that bad, specially now I see my kids use it to the max (and I use Excel as well since where I work uses Office as well). I had been using OpenOffice for 2 years and I like it because it is free. But after using Office 2013, its worth the money na rin. And its not much of a hassle to pay because I use my Paypal account to settle it.
