Another minor quibble: all the laptop's ports have these rough, strange little gaps around them. The ports are unusually tight around USB devices, to the point where I need to exert some force to remove my thumbdrive.
There's a weird thing going on with the Envy 13's charging, too. At some points during the charge cycle, the laptop's processor gets very slow -- enough that it takes several seconds just to switch between tabs in my Web browser. I've seen the issue on three different review units.
To be clear, the processor is fast when the laptop is unplugged, and fast when it's fully charged. The only time this shows up is when you're trying to charge it up from empty and use it at the same time.
It may have something to do with the computer's BIOS. When HP they sent me a third unit with an earlier version of the BIOS, it seemed to work OK...but as soon as I upgraded to a newer version, the issue reappeared. (HP is still investigating.)
