I must confess to being a bit of an iPad convert...
When they first came out, I thought it was just a yuppy toy - or a big iphone with no phone capabilities!
Then, after the iPad2 came out I looked closer... Since I spend my entire life either coding or online with SEO tools, I thought an iPad may come in use in my home office.
And sure enough... once you've had one for a few weeks, you'll never want to be without one.
Comm's/Skype/email etc via the iPad is a joy, and everthing is just so instant. I spend a lot of time researching on the web and browsing with an iPad is great too - and the lack of Adobe Flash doesn't really bother me. I've always felt that any site that integrated flash so heavily that you can't even use it without it was crazy anyway, especially when JavaScript/AJAX/PHP/CSS etc can do just about anything these days - and it's more compliant.
So... I haven't moved my coding to the iPad yet, but I could definitely use one (as long as I had a keyboard) and a decent editor, since most of my code is php/web-based anyway.
