Welcome the iPad
Apple's new device may not be a surprise but on the basis of technical innovation it is very welcome. From what I've seen we're looking at a luxury good with entertainment at its heart and business use on the back-burner. 3rd parties may come in to fill the gaps. That said, Apple is renowned for vendor lock-in despite have one of the most evangelistic customer bases.
In its infancy I see this as a toy for the well off. This first version is a little repressed, most likely in an attempt to avoid cannibalising the iPhone. For example it doesn't have out of the box call making functionality, despite being equipped with microphone and speakers. I haven't found anyone with a good reason as to why it doesn't have a camera, apart from the obvious unwieldy size of the device. The back lit LCD screen puts a question mark over whether it will be a Kindle killer.
The first impression when I looked at it was "where's that going to go?" Laptops are delicate enough. I'm precious over the screen on my G1 phone. How do I keep this in use, yet out of harms way? Try keeping the kid's filthy mitts off something as cool, flashy and responsive as that. Rules out the coffee table.
I guess I'm more excited by its Star Trekkie nature. I can see it as the stepping stone to changing the way computer devices are moving. Not enough in it for me to cough up the dough but great progress none the less.
