It's entirely down to the kind of projects you're working on. Most of my work experience is with agencies, so I've had a good mix of clients with new and legacy clients. Some industries have a large number of legacy users, whereas with some clients it's strange to see any IE, let alone an older version like IE7-8. A client I worked on a year ago had around 20% of users on IE6-7, and these were users in the UK and not in China or Russia. The explanation given by the client (who spend a lot of money on web analytics) was that many of their users were business-based, and a lot of companies in the UK are restricted to IE6-7 and Windows XP due to internal web software. I used to be of the opinion that developers should support older browsers, and should gracefully degrade when used on legacy browsers. I think this was probably because I thought that things would change after a few years. Four to five years later, and IE7 (and IE8) are still a problem, and since corporate users won't get off of XP for a few more years I think enough is enough. I am happy to support older browsers when there is a business case for supporting them (i.e. there is an existing user base stuck on these browsers), but if you're working on a new project then IE9 should always be the minimum, and degraded view.
