Website Design: 960px outdated?

[Scottland]

For a while now I've been using 960px as a starting point for a websites max width. When looking around the net, a lot of guides and tutorials suggest using this width or one close to is.
A lot will also tell you to base any mock ups on http://960.gs

However, I do wonder if this is a little outdated now? More laptops than ever are being sold and most with a 1280+ display. Small 10" tablets are coming with the same res screens, and desktop monitors are generally 720P/1080P these days too.

Recently I've been playing with a 27" iMac and some websites look minuscule on it!

Is now the right time to start experimenting with different widths and sizes? What are your thoughts?

websites that demand a large (>1024 screen) are downright annoying . Newsflash - we don't all want to browse the net with scrollbars or maximised windows.

No I agree, I wasn't suggesting 1800px wide - but something beyond 960?

Has anyone ever played with custom stylesheets depending on screen resolution?

Thanks for all the responses guys - it's good to hear other people opinions etc.

Been reading quite a bit on responsive designs this last few days, this article I thought was very good.
