Switch back to feature phones from Smart phones effectively

How can I switch back to feature phones from smartphones? What are the advantages of feature phones over smartphones? What is it like to downgrade from a smartphone to a feature phone? How to prefer tablets over smartphones?

First of all, let me list the positives of preferring a feature phone over Smartphone :

1) Battery duration: Smartphones are huge battery hogs. Most smartphones don't last for 24 hours without recharging. But most of the feature phone lasts for a week. If you are always on the go and don't always remember to charge, feature phones are the best. Now, you can have a weekly reminder to charge at your own convenience.

2) Reliability: Imagine that you are in an emergency situation, you pulled your smartphone out, only  to find that it had hung and won't reboot in a long time. Seriously, it is stupid to pair  extreme complexities of entertainment+gaming with something that is  essential: phone. Having cut those entertainment attributes, you could shop for a phone & network, purely on one  attribute: reliability of voice communication.
3) Distractions: Smartphones  add an array of distractions to the existing pile of distractions. Walking on the street and you see people like  zombies lost in their own world of games/music/communication apps.

4) Wifi availability: In the past 5 years, Wifi hotspots have become ubiquitous. Thus, I am suggesting a combination of feature phone and a tablet/laptop instead of a smartphone. You can use your iPad to get the job done on most occasions.

5) Screen size: Tablets provide an ideal compromise between phones and laptops. After the arrival of iPad, It isn't satisfactory seeing things on a micro scale.

6) Data costs: You may no longer need to pay $100 for unlimited data + voice. You can effectively save something out of your monthly budget.

7) Get out of rat race: Once you are addicted to the smartphone and built an image that way, you will have to keep up with the latest of the gadgets/apps all the time. It isn't worth the time, especially when you are competing with the common masses.

8) Data loss/privacy: You could lose a phone pretty easy (I have lost it once in an airline security check). Losing a smart phone can be pretty serious (think of all the data that is there, accounts connected and payment services enabled). When you have a feature phone, you don't lose much more than the contact list and a few SMSes.
