No, most phones can get email fine. it's just that setting them up with your email accounts requires a masters in computer science.
Even if more people can happily receive MMS's, doesn't mean that it's something that companies should support going forward. As soon as a company like apple adds MMS to the product, there is no way they can remove it, when people get sick of the low quality photos. For example a lot of competitor phones are coming out with cameras with 5megapixels or even larger. We're talking 1000s of pixels wide here folks. MMS can only support up to 640*480px (feel free to read over the specifications:

What all mobile phone companies should do is work out ways to improve email support, and email setup wizards and the like. As email will provide the gap between mobile device, and desktop as well, while also providing the capacity for high resolution multimegapixel images.
