I went Epic over Evo. Its largely preference though.
Screen - 4" SuperAMOLED (Epic) vs 4.3" LCD (Evo)
Size - ~14mm (Epic) vs ~12mm (Evo)
Keyboard - Landscape QWERTY (Epic) vs On Screen (Evo)
Software - TouchWhiz (Epic) vs Sense (Evo)
Processor - Hummingbird (Epic) vs Snapdragon (Evo)
Other than the processor, where the Epic is the clear winner, and the thickness, where the Evo is the clear winner, the other categories are all pesonal preference.
The EVO is actually 13mm thickness.
For a non-keyboard phone, its quite thick comapred to today's standard.
Because of my lust for the HD2, I was always quite fond of the EVO because after all, its an HD2 with Android but after playing around with it a few times now, I wouldn't get one.
Although its almost identical to the HD2, its thickness and added weight is a big negative for me.
And since I've gotten my hand on a Captivate, I hardly use my HD2 anymore.
The Captivate is thinner and lighter and it does make a difference.
I think the EPIC is better in everyway over the EVO except for 2 things.
- I don't like slide out keyboard. I have no use for it on a big touch screen smartphone. I'd rather trade it for thinness and less weight.
- I don't like the rounded design. I'd prefered a more square-ish device.
I wish Samsung had made the Captivate have all the features that the Epic have.
