Browser Statistics - Is IE7 reclaiming ground for Microsoft?

Browser Statistics - Is IE7 reclaiming ground for Microsoft?

  
At the end of last year, there was some discussion on just how would IE7 affect the competition browsers' steady growth and the web development practices, as a consequence.

Taking a look at the W3C stats, we have this distribution, currently (http://www.w3schools.com/browsers/browsers_stats.asp):

IE6: 37,3%
Firefox: 32,9%
IE7: 19,2%
IE5,Safari,Opera,Mozilla: ~1,5% each

On of the most interesting trends is that the climb of IE7 was made by stealing IE5 and IE6 market share. Firefox gained another 2% since the beggining of the year.


According to these numbers, whichever the error margin, one thing is now for granted:

WE ARE DEVELOPING OUR WEB APPS FOR 3 BROWSERS!

Have this in mind during your development, and, specially, for your project estimates. This fact has increased importance for non-standard-styleguide projects.

PS: I recently came across an online survey for the "better browser" - 70% of the users preferred Firefox, with Safari and Opera ahead of IE. Just a survey or a future trend?
