Turn Your iPhone Into A Computer With A Portable Keypad
I used to go around Paris with my PDA and a foldable keyboard that hooked up to it. It meant I could write at anytime, anywhere -- I just had to pull it out of my purse.

Likewise...why lug your laptop around when you can hook up a portable keyboard to your iPhone to write down your ideas without pecking around on your screen keyboard like a chicken? From Amazon ($35.99) -- a regular-sized keyboard that folds up to pocket-sized:

iClever Bluetooth Keyboard, Foldable Wireless Keyboard with Portable Pocket Size, Aluminum Alloy Housing, Carrying Pouch, for iPad, iPhone, and More Tablets, Laptops and Smartphones

This one's for Apple and Android, and comes with a touch pad! (However, it's a mini keyboard, not full-size like the other folding one). $21.99!

Fosmon Portable Lightweight Mini Wireless Bluetooth Keyboard Controller (QWERTY keypad) w/ Built-In Touchpad for Apple / Android / Windows Smartphones, Tablets, PS4, Laptop, Notebook - Black & Orange

Here are some other phone keyboards.

Also, you can now search Amazon for any item in a search window now on the left sidebar (thank you, Gregg!). It's just under "SEARCH BLOG."

Here's the Amazon legal thingie about that search bar and regarding any links to Amazon that appear on this site:

"We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to Amazon.com and affiliated sites."

And in case I'm supposed to include the newer legal thingie about Amazon links on the site:

"As an Amazon Associate I earn from qualifying purchases."

PS Post inspired by paywalled WSJ article I can't get into but maybe you can. (It reminded me of my Paris PDA-typing-in-cafés days.)
