Day #3 for me here at Macworld and I just got done checking my email on a iPod touch. I use Yahoo! Mail Plus for email and the constant resizing -- i.e., to unreadably small (even in landscape mode) for each new email is a drag. The Apple folks here say that what I'd need to do is access my Yahoo! Mail using IMAP, because the native Mail doesn't resize emails for each page load like the Webmail clients do. Before I buy the iPhone, I'm going to need to get this email biz sorted out as that's one of the primary reasons why I'd be buying the thing.
