We own an ipad 2 each, which we use for note taking, sketching, surfing the net(research mostly), emails, photo storage, Music applications, and some pretty neat apps which can be productive or fun.
Storage: 16gb
price: Expensive lol - we bought ours as a gift to ourselves for a really hard years work, back in 2011
Screen size: 9.7 inch
CPU: Dual core 1Ghz.
Ram: 512mb
Resolution: 1024x768
The only thing i can say about the ipad, is the touch screen is really well made and works 99% of the time, when compared to other tablets and phones such as the Galaxy S2 Phone, which seemed to need a lot more press.
Also the ipad is really durable, especially when dropped as it has a metal backplate.
They are quite limited in what they can provide you for an added development tool. But they are great fun as a Big boy toy lol.
We really want a 17 inch touch tablet that houses windows, so we could use skyline with a touch screen lol.
But they are a tad expensive atm.
