Nothing irritates me more than a site not working on my iPad. I use my iPad for fun and to get away from all the responsibilities that come with my laptop. I don’t check email and I try really, really hard to not check Twitter. My husband, my son and I all have iPads and we all use them daily. There are way too many websites that have either not been updated or didn’t plan to work well on any type of tablet and I think everyone should be focused on a site that works for everyone (and every browser please).
Journalism.org released an infographic based on a study. You can view it below and please look at the data closely. You, your friends, your clients, your family and everyone else needs a site that works well on tablets. This IG is focused on news, but we all know that people are using tablets to look at everything. Take the time and money to invest in a site that works.
TO CLARIFY: A lot of comments are taking what I said above and assuming I am talking about Flash and the iPad. This is not the case. You can have Flash and your site can also work on an iPad. I am talking about coding issues that prevent the site from working correctly.
