I used to use my iPad most until I traded it in for a Wii U. Haha. I tend to use my desktop for internet most. I have a netbook that is a piece of garbage for anything and it only works because I have Linux installed on it. Otherwise it would be too slow to do anything except text editing and even that is an almost impossible task on it.
I do however find myself using my HTC Sensation smart phone to browse Reddit and check my emails a lot more now that the iPad is gone. I miss my iPad.
The reason the iPad is my favorite is that it was quick and easy to use no matter what I wanted to check up on on the internet. The smart phone is slow.
But at least it's convenient.
