iPad owning Android fan
When I was looking to get a large, good tablet after I initially bought an Advent Vega (great price at the time, still runs great with community ICS!) I had two real options. Those were the 3rd generation iPad or the ASUS Transformer Prime. I wanted to get the ASUS, I was ready to spend my money and be happy with what it gave and then ASUS gave the UK no options. You either bought the 32GB version with keyboard dock for £499 or you do without. They lost a customer there by doing that and I imagine I won't be alone.
The iPad had a higher resolution screen and cost £100 less, sure I knew it was a walled garden but the screen was more than just specs. to me. I'm a DSLR owner trying to learn by practicing and unfortunately trying to review images on a camera display has shown me that I can't rely on it to tell me if I got a decent image or not. I can't really tell if I lost detail, had a bit of movement that blurred the photo or if the highlights meant I lost what was in the shadows. I bought the camera kit / USB connector and now I just hook the camera up and can see almost instantly what it looks like. Could I do it with another tablet? You bet. I'm not saying this is unique to the iPad at all, just explaining my reasoning behind the purchase.
I still hate Apple and their "shiny shiny" mentality but for pushing resolutions up and making other companies give me choices of products I wanted for years before the iPad I grudgingly acknowledge them.
