The most powerful Windows Mobile device I ever evaluated was the HTC Advantage X7501 that was released back in August of 2007 and I wrote quite an extensive review that was my most viewed blog post of 2007. The successor to the Advantage X7501, the X7510, was announced at Mobile World Congress in February of this year. I was able to see the T-Mobile version at the show and play with it for a few minutes and have been looking forward to seeing the device released ever since. We were in a session with Eric Lin, from HTC, at Mobius last week and I was asking questions about the Advantage when Eric announced that each attendee was going to be receiving their own HTC Advantage X7510 at the event. Needless to say I was shocked and extremely excited since I have been using and thoroughly enjoying the original Advantage since last summer. I was actually using the Advantage paired with the Celio REDFLY to take notes and keep up on events during the conference last week. Check out my image gallery, video and thoughts/experiences with the device to find out if I think this latest model is a worthy upgrade for existing Advantage owners.
