I am curious why he would want the X over the EVO? I loved my HD2, but hated T-Mobile due to poor 3G signal strength. Wanted the X, but none were available, so tried the Samsung Vibrant (which proved it was not my HD2, but their poor 3G signal period!) and Captivate. Most of my time with those were just trying to make their TouchWiz desktop to look like the Sense UI, using Beautiful Widgets, but it was buggy. And the e-mail programs, ugh!!!!!!!! The OEM, K-9 (basically a slightly tweaked OEM version), and MailDroid were total garbage! And the sms/mms were too, compared to what HTC Sense UI offers. So basically, to get a phone similar to my HD2, but one a better carrier, it was the EVO hands down, and no regrets yet.
I will admit that the X still intrigues me. But from what I have seen, their Blur (???) UI does not impress me at all. Looks so lacking and plain compared to the Sense UI, would I once again be spending hours trying to make it look like Sense again? And how is the e-mail and sms/mms handled on the X? If it is as poor as on the Samsung Galaxy S phones, or in need of the K-9 or MailDroid programs, totally unacceptable.
