Currently my office uses WordPerfect version X4 (from Corel Office Suite x4) as our primary wordprocessor, a 1999 version of Timeslips for time keeping, QuickBooks Pro 2000 for our accounting, Adobe Pro 11 for our document handling & SyncToy, which I have stopped using since I went to a two device solution about two-and-a-hald years ago. We might as well have Lotus Notes running RAM resident. I don't think we would have any problem sticking with the 2016 version of OneNote if it wasn't for the Samsung Note 5 (which I'm sure to be upgrading within the next model or so) and the changes that are sure to come to OneNote Android. I am assuming that it will no longer sync with OneNote 16 after MS goes completely to the cloud. My current combination is a killer application for me. I don't really want to change it. I just want the devices to keep up with power and storage upgrades in the future and for the software to work together. I'm sure there will be some inconvenience if we stay with OneNote 16. We put up with that with WordPerfect for quite some time. Just about everyone on the planet uses Word. So, for the few times I am involved in transactional work, like contract drafting, I have to switch to word for redlining. I can see why transactional lawyers and other users who do a lot of redlining are forced to use Word. On the other hand, where the software is isolated from the public, as in accounting and time entry software, we have just stuck with what got us here. If it ain't broke … In large part, we have been able to stay with WordPerfect x4 for at least a decade longer than the rest of the world (probably longer) because I have a trial practice. Nothing is better than WordPerfect and the reveal codes function for drafting pleadings. Word is far, far inferior in that role. I could not imagine leaving Windows and starting all over with another OS. I am wedded to Microsoft in that regard until the company makes it impossible to continue without a complete revamping of the firm's software. I guess at some point, Microsoft will stop these legacy programs from working in their evolving OS's but hopefully, by then, I'll be in a nursing home, gumming apple sauce and babbling a constant stream of mis-remembered stories of my life to the staff.
