Excerpt from review of HTC Hero from engadget.com
The Hero represents a valiant effort from HTC -- though unfortunately, the company appears to have bitten off more than its last-generation hardware can chew. If this build of Android were to be loaded atop the guts of a 3GS or Pre, the performance would likely be astounding, but fused with the two-year old architecture of previous devices, it's mostly disappointing. We're not saying this isn't the best build of Android on the market -- we think it is. What we are saying is that this build is a bit too much for a device like the Hero to handle, and that makes for an uneven, sometimes frustrating experience. Going into the review, we desperately wanted to love this phone, but given the combination of a few poor hardware choices and an OS which outclasses the device it runs on, we can only recommend that you enter at your own risk. HTC has an explosive entry in the smartphone category with what its done on the software side... now it just needs the hardware to match.After reading this I think I should wait for at least 6 months before getting a real android device.
