I barely use my iPad anymore

I feel the same way about smart-phones. There are very few apps I use that are really game changers.
The smart-phone replaced an existing piece of hardware, so it isn't like you were going to leave it behind, but I'm not so sure about the tablets.
I've got a Kindle for reading, and have very little interest in a tablet. Still questioning what would I do with it??
I went from an iPhone 3G to a Motorola Droid to an LG Optimus V running on Virgin Mobile. Though the Optimus V is in virtually all ways a step down from the Motorola Droid, $150 for phone + $25 month for unlimited data & text and 300 talk minutes is such an enormously better value and the Optimus V still does everything I actually used my Droid for just fine.
YMMV if you care about running the latest 3D games (or Flash, since the Optimus V has no Flash support due to being ARMv6)), but I've been totally happy with my "downgrade".
But I still use it 5-10x day and increasing.
