I won an iPod Touch a few months ago. It is a wonderful device, and it is attached to me in some way for most of the day. I have it fill in background noise when I need to think at work. I use it as an ebook reader, and view the wide range of PDFs and documents I want to read on the train.
I track my expenses on it, listen to Podcast lectures, read the news, keep my todos, make shopping lists, play games on it when I need to unwind. I'm going to start taking it on runs - using it as a pedometer. Sometimes I even use it to listen to music - streaming from my music collection over my house network.
What the iPod does is very simple: it allows instant access.
That's why I'm completely besotted with the little Eee PC. The cheap little Linux laptops are built for the same reason - instant access to what you need.
The problem with using conventional computers is they require a "session". When I use my computer, I think about it as Something To Do - it will take time to load the system, the program, the internet page. Often its in the wrong room. Even if its a laptop, one must sit in a certain way to use a laptop - because they are usually so heavy.
Not that this is a major problem, but computing and the internet as Something To Do is how the iPod Touch/iPhone and Eee PC (and other "netbooks" or internet tablets) are a step forward. They remove the "session" thought process and allow immediate connectivity. What about mobile phones? Yes, they can also do it - but that isn't what they are for, and the frustration of interface means that the "session" mentality is still there.
The Eee PC is much different from the iPhone/iPod Touch as it allows a full internet and computing experience. With its small, light footprint, long battery life and quick boot time, it is highly portable and does not require a time commitment to use.
Its going to get better too. Open projects like Google's Android and OpenMoko will allow this new always connected internet to be disconnected from iTunes. The blurring between online and offline apps and widgets mean that the layer between the local and cloud gets more and more removed, while services fit closer around users needs and interests. I think its very exciting.
