I have a question that I think will be pretty basic for the level of awesomeness that exists on this site. Please bear with me as I am not nearly as smart at this stuff as you guys are. I'm moving to Brussels in about 6 weeks and need a new phone. It has to be unlocked so I can use it with a European SIM card. I really want the HTC One because I've had an HTC phone for the past 6 years and haven't had any problems with them. Not to mention that it looks amazing. However, I do have some concerns with the lack of external memory. I don't think the 32 GB will be enough for me, and it looks like the only option for the 64 GB is the Developer Edition. I understand that it comes with an unlocked bootloader and that this may invalidate some external apps because of invalid DRM security keys. My question is, for someone that isn't going to install a new ROM or hack anything, will this be a problem? I just want a regular old cell phone with a lot of memory. I'm not smart enough to unlock and lock or root and unroot stuff.... so I'm not sure if by choosing the Developer Edition I'm getting in over my head. :-\ Any advice would be much appreciated!
