If you have used it before, and you don't like the current incarnation (and the usual gyrations you have to go through to customize window borders, mouse pointers, docks, etc.), you may want to give Extix a try. It has the Mint 16 type of dock (pain to install in Ubuntu) and it is a little easier to customize the window borders, etc. It's three downfalls is the PDF reader (same for most Linux distros) which don't print correctly if it was written in Adobe PDF, setting up network printers will necessitate going to a command line (sudo system-config-printer, iirc) and there is no screen saver. But I like it more than the last 4 Ubuntu versions and the last 3 Mint versions. Gnome3 hid a lot of the customization settings, so it will take a little more work to setup a machine to your liking.
I am a computer technician with 40 years experience. I will not use Windows to purchase anything on line. At work I use XP (now off-line - no internet access), W7 and W8. If I want to buy something on line I will boot up from Linux Live CD on SD card (home) or USB (work). I give all my friends who do on-line banking Linux Live CDs. Tails, Ubuntu, Mint, Extix, Gentoo, BSD, SUSE, RedHat, et. al. - any plain Linux is better than any Windows when it comes to on-line banking and on-line purchases; some secure distos, like Tails, may present problems to the end-server since the packets are scatter routed instead of in a one connection stream. For instance it may not take your credit card and security code. The trick is trying out a few distros until you find one that works flawlessly. You boot up on the CD or USB, start the internet browser, do your banking, close the browser, shutdown the computer (the distro will instruct you to remove the CD and hit the carriage return key; it will then power down the computer.)
