It is bigger than the outgoing model but the design is beautiful and it runs nicely. Battery is still so so . SD card really isn't a problem. Every htc I've owned has given either free google drive or dropbox space but I guess if it's important to some then that's a good. Flexibility is the key. Screen is slightly different. I have the m7 and side by side there is a slight warmth to the whites on the m8. Still a nice screen. I'm happy with the upgrade.
