If you need something small, you can run kali in a raspberry pi, is small and way more cheaper.
I like the pineapple concept, but if you see the hak5 videos, they promote it like a impressive tool, but in real life, is not reliable for the price you pay, most of the time doesn't work.
About the support, take a look at the forum, see how many questions were answered, how much does it take to get an answer and you'll get an idea
I think the pineapple has potential and someday would be a great tool, but right now, is just an expensive paperweight.
So my advise is use a raspberry pi or those small old mini netbooks like this.
