I was playing with the Galaxy tab recently and I have to admit that I was reasonably impressed - I'd say 86.4% impressed.
So along with iPad, iPhone and Android phones, we are now looking at a pretty big group of people on the Web using these new types of Web surfing devices. I think web designers will have to take notice.
...HTML5 and CSS3 comes to mind.
Fortunately though, if you are using standard HTML 4 and CSS2, your pages will look fine on all these devices. HTML5 and CSS3 just take things to a whole new level.
Anyone developing for iPads or Android devices around here yet?
