Although we migrated to Mac in 2009, MS Office has always been, and continues to be, an essential software suite for us. MS Word for documents, MS Excel for spreadsheets, MS Powerpoint for presentation slides, we use those three daily. I have not tried MS OneNote for taking digital notes, and do not currently use MS Outlook although both are included in the bundle of MS Office 365. All for less than $100/ year for up to 5 users. A bargain - and a five star product!
