I too agree that having these details automatically updated on the menu buttons would be a great thing. When I'm wondering what the weather is like outside I'm not looking for intimate details - I just want to know what the temperature is and whether or not it's raining. If I can do this by merely powering on the iphone that saves me precious seconds, and those seconds may not seem all that important at the time but after a few weeks they become saved minutes and after a few years they become saved days. After decades of iphone use those few seconds translate into weeks. Wouldn't we all like the equivalent of a few extra weeks added onto our lives?
Similarly if the Stocks button could automatically be updated with my favourite stock quote, if the clock could show the current time, text message button showing updates, etc., that would save me even more time that I could use for other purposes.
Anyone who wouldn't want such things must be tired of life. Personally I love life and I would enjoy it all the more - and longer - if I had faster access to certain information.
So here's a vote for the iphone's buttons for weather, stocks, text messages, the clock all featuring automatic updates. In my view a person would have to be an idiot to vote against such time-saving conveniences.
