Seems as if I will gradually be leaving behind a lot of the programs I have used for many years on Windows, purely for some consistency in having things on all my devices and knowing how things work in them. I'm stuck with needing to do this with iPads for now, but longer term am likely to be able to give that up and just go with Windows/Linux and Android. Very surprised at how few programs seem to be available on all these platforms.
Office-wise I decided to upgrade to Office365, but also have Softmaker and Google apps I can use instead. But I've also been reminded that my preference is for database based programs rather than having everything saved in individual files.
Evernote probably works better the more it is used, so that's fine. There is very little that it does really well but being available, syncing well and doing a lot of things makes it really useful.
Mendeley works well on iPad and Windows and Scholarley isn't too bad a mirror on Android.
Lastpass is ubiquitious. And even without checking I'm sure Truecrypt and Keepass will be there too.
Handwriting/drawing apps rarely seem to cross platforms. Note Anywhere does, and does most of the things I want, so I will probably go with that although its functionality seems to vary massively from one platform to another.
Outliner/writing programs will require my biggest change and most seem to be on one platform only. Scrivener has versions for Mac, iPad and PC and the Android version is supposed to be coming in the next month or two. I've tried Workflowy and can see what it does and why it should work for me (and why it might be better than many of the progs I have been using), but it's not going to come easily, so may well take the usual year or two, or three+, before I get into it.
PS I absolutely hate W8. Might be designed for touch, but it doesn't work well, let alone compare to iOS or Android, and the store has so little detail and virtually no reviews.
