I set up my iGoogle start page yesterday. I have news feeds from two papers, the weather report, and a daily Oscar Wilde epigram. And briefly a copy of Space Invaders. I was happy with the 'Classic' theme, but Margot told me I was boring and made me look for one more distinctive. I ended up with a photograph of boats moored at Port Said.
I understand what iGoogle is now. I'd expected to be able to add any site with an RSS feed to my page. In fact, you assemble your page from purpose-built applications: gadgets. It's another Google product, Reader, that works with feeds.
Playing Space Invaders at work reminded me that the PC games I played as a boy sometimes had boss keys. The boss key would pause the game and display a spreadsheet (that is, while your boss walked past). Of course on a modern windowing machine you just hit Alt, Tab. I would imagine.
