I'm currently reading both of these books and really enjoying them. Learn Vimscript the Hard Way is obviously a hard read, but good. It's also available online for free, but I've enjoyed having a physical copy.
I really have enjoyed my first mechanical keyboard, which is the Das Keyboard 4 Ultimate Clicky. It has no numbers or letters on the keys, which forces me to use the keyboard correctly, and to learn where all the keys are (even the less used ones). I also love the feel of the clicky keys. It just feels really nice to use. Also, it feels really durable and well made. It's a keyboard I'm proud to have on my desk.
