The smartphone market moves at an amazing clip today and in May I put together a top 10 list of smartphones at the time that has radically changed over the last couple of months. I also mentioned top smartphone on each carrier in June and would make at least one change to that list. You could buy a Nexus One and use it on T-Mobile, but it was never sold through the T-Mobile retail channels and all the other Android devices were more mid-level quality. The T-Mobile Samsung Vibrant has now changed that and rises to the top of the heap for T-Mobile smartphones. I thought the HTC HD2 would be that top smartphone, but the device let me down too often to take that spot. I have been very happy with my Sprint HTC EVO 4G and wasn’t really thinking I would buy my own Samsung Vibrant on T-Mobile, but I didn’t have a high end smartphone for T-Mobile so I decided to swing by the store and check out the device. After just about 5 minutes of playing with the Vibrant, I went to the counter and found out I was eligible for the $199.99 price (after $50 rebate) so I quickly paid and was on my way. I have now spent several hours with the Vibrant and personally find it better than the Nexus One is several ways and am even enjoying it more than my EVO 4G at the moment.
