It's come a long, long way over the years:https://tails.boum.org/
Verify the downloaded image with GPG4WIN:http://www.gpg4win.org/
Use persistent storage with at least two keyring files:https://tails.boum.org/doc/first_steps/persistence/configure/index.en.html
Run off a micro-SD card (easy to hide and/or destroy, if necessary):http://www.walmart.com/c/kp/micro-sd-cards
(Buy directly at Walmart and not through the Internet. And, create four or five "spoofs", which goes without saying!)
When starting tails, use the TrueCrypt option:https://tails.boum.org/doc/encryption_and_privacy/truecrypt/index.en.html
Create and store your TrueCrypt container within persistent storage with a MINIMUM length passphrase of 30 characters (Upper & lower case letters, numbers, punctuation & special characters -- easy for you to remember but impossible for others to guess, and, of course, do NOT write this down anywhere, which means "Practice, practice, practice"!!!) and use two or three keyfiles!
And, αnσnymσus Wi-Fi hotspots:http://www.howtogeek.com/196186/how-to-find-free-wi-fi-hotspots-when-travelling/
("Never the same place twice for maximum security!")
Use αnσnymσus email and only access via the Tor network:
(That's an '.onion' address.)
Use a tablet:http://www.walmart.com/browse/tablet-pcs/computers/3944_3951_1078084
(Once again, buy off-the-shelf.)
ENCRYPT EVERYTHING (especially, email)!!!
