I have heard the power draw can fry the board on a Laptop & PC's and people have had it happen, I just don't think it is a good idea to risk a $1,000 or more piece of precious equipment when you can use a wall adapter to go from AC/USB and get great power this way. I guess it's all up to the individual user but personally I plug in my PT to the wall adapter and get a strong 110 to my adapter with no risk to my PC
I don't doubt that it can happen - but it can happen with anything, I suppose that's all I'm saying. If you use your computer's usb ports to charge your camera or cell phone, or use a mouse, there's always going to be a chance of failure with any device that draws power through your computer. And granted, the other PTs don't "look" like the ego pt, either - what with their inline battery.. they just
look kind of sketchy.
But I'm still thinking if your motherboard is gonna fry, it's gonna fry. Having said all of that, I actually use a wall charger most of the time just because I hate cords cluttering up my laptop space so I have a less obtrusive setup, but if I'm on the laptop in another room, I don't hesitate to use the usb.
Some of that might come from the quality feel and standard 5pin cord, though. It is confidence inspiring, somehow.
But I promise I'm not twisting anyone's arm to do the same.
