McPlot is correct. One of the best selling points for the HTC Bolt is support for 3x20 MHz Carrier Aggregation. Which is super fast! Sprint has started to deploy three-channel carrier aggregation many markets (Chicago, San Francisco, Minneapolis, Dallas, Denver, Kansas City, Cleveland and Columbus). If you happen to be living in one of those markets I would certainly take the HTC Bolt for a test drive. Other things many customers are looking at is the slightly larger screen (5.5"), the included Hi-Res adaptive headphones (earbuds) and a having a general preference towards HTC. I've compared the Bolt head to head with an HTC 10. I only found trivial speed differences (in terms of CPU) and the Snapdragon 810 is nothing to discredit in terms of speed and suitability. You also get Android 7.0 right out of the box which the HTC 10 hasn't seen yet. If you're a fan of HTC, don't knock anything till you check one out in person. The HTC Bolt is a very nice phone overall.
