Same here. iPads are for content consumption, and not creation, IMOHO. Ours gather dust, when the kids aren't playing Minecraft on them.
I recently looked at migrating from an iMac to a 15 rMBP. At the end of the day, I went back to the iMac as my main system. It just did more of what I needed, and I typically need horsepower and screen real-estate, from my desktop.
Surprisingly, I wound up with a 12 Macbook as my mobile. It's practically the same size as an iPad, but I can do real work with it. It's soooooo small and light, yet powerful enough to do 90% of what I do for work. My iPhone takes care of the rest.
But when I really do need a tablet, I reach for the Surface Pro 3. that thing is growing own me, and does a few work things where I still need a PC. I was pretty much intent upon it being my laptop and tablet, until I bought the woman a new MacBook. So now, when I travel, I throw both the SP3 and 12 MB into my bag.
Beefy iMac and Svelt MacBook is my combination, with the SP3 thrown in for good measure.No need for iPads.
I think that if you do NO WORK then the iPad is fine. Go for playing with apps, checking email, surf internet, watching movies, chat. But if you want to do real WORK, you need the MacBook. JMO
