Chuck, I want you to know that I respect your post and your thread, and that this kind of thing (avoiding arguments) is the type of thing I have been railing against in other threads. I am going to to try to avoid any such arguments here and am going to limit myself to posting solutions as you have requested. Hopefully the arguments are not brought up by others.
There is one preliminary item I think it's important to clarify however, given that its fundamental to how many Blackberry 10 tasks and uses work. Blackberry ID, Blackberry Protect, and related services have been specifically exempted by Blackberry Limited from EOL status, so they are NOT EOL at the end of this year. The BB10 OS however IS EOL.
To answer your question, I would argue ALL BB10 hardware is usable beyond e-mail, phone calls, and texting. Here are my recommended basic solutions for common smartphone tasks:
(OS Version Disclaimer: Upgrade to 10.3.3 for all devices capable. Your device will run much more smoothly.)
1. Backups: this is a fundamental concern for anyone having data on their phone. I would recommend the following for backups:
a. On Computer--Use Sachesi or Darcy's Blackberry Tools on a scheduled basis to
back up all data including apps and app data.
b. Cloud--sync your BBB files to the cloud storage provider of your choice.
c. Device to Cloud--map your BB10 device as a mapped drive on Windows/Mac and
sync that drive to the cloud storage provider of your choice. This will not take care of
apps and data, but will handle files.
d. Device-Only Backups: purchase and use Ultimate Backup from Runisoft at
Home and back up directly to your SD card, syncing to cloud if you so
choose.
2. Browser: if you have trouble with the existing BB10 browser, install BEOL Browser. It's an Android app but designed specifically for BB10 and will handle all websites.

3. Facebook: Use FacePro or F5 natively or, if you prefer, Facebook Lite in its Android version.

4. Twitter: Use Neatly natively or Blaq if you have it (or can download it if I'm able to get it from the dev and release it on the thread in the CB BB10 Apps forum.)
5. Instagram: Use Inst10 natively.
6. Spotify: Use the Android version, available here:

7. Navigation: Use either Blackberry Maps or, if you prefer, a Google Maps wrapper.
8. Any Google Apps: use Cobalt's method and the older versions which still work with said method.
9. Streaming Your Own Media: Buy Kalemsoft Media Player from
www.kalemsoft.com and set up the corresponding Streamer app. It's like Plex for your BB10.
10. Streaming Other Media: use the Netflix/Hulu/whatever Android apps that are compatible. I am working on adding those to my known compatible repository.
11. Podcasts: Use bPod Podcast Manager, a native app which has been released by the dev.
12. Playing Local Music: Use Neutron Media Player or Kalemsoft.
13. YouTube: Use FastTube natively, or failing that or StereoTube use an Android app of your choice.
There are many other solutions for specific use cases but that covers many basic functions for which people use a smartphone.
If I've missed the point of your question Chuck let me know and I'll clarify, but hopefully this helps answer it seriously and points people in a good direction....
