LTE is well-trodden territory for HTC, thanks to its previous dalliance with Verizon and the Thunderbolt. Sadly, the Vivid falls short of clearing a few performance hurdles, but if you absolutely must have an LTE device on AT&T, it's not an altogether terrible choice. Does it benefit from the company's early experience with Verizon's LTE? Somewhat: there are noticeable some noticeable improvements in battery life, and HTC's Sense 3.0 UI is more refined this time around. Where the Vivid falls short, though, is in the looks department. It doesn't fall completely into the trap of being a juice-deprived paperweight, but that's going to take a lot of attention to settings adjustment on your part. When you compare it side by side with AT&T's only other LTE phone, the Galaxy S II Skyrocket, the winner is clear: Samsung's offering puts the Vivid to shame. It's lighter, faster, sleeker and packs enough battery power to really let you surf those blistering 700MHz waves. Really, though, the decision boils down to your budget. With an on-contract price of $199, the Vivid is the cheaper option of the two, but only by $50. Seen from this angle, all that separates you from a lasting and stylish LTE experience versus a chunky, underpowered weapon of Sense 3.0 destruction is a mere fifty bucks.
