While I'm enjoying my newly acquired N5 I must say this is my last Nexus device. It's a great phone but it has it's downsides. I think Nexus line is going downhill. This phone has a faulty mic (or the noise cancellation; either way, making calls is problematic), the camera is meh (not bad but I wouldn't say it's something awesome), the screen is meh (coming from the SAMOLED Galaxy Nexus I just can't love the IPS's backlight). The loudspeaker is nothing special and my 3 main gripes - the nonremovable battery, the difficulty of field-switching SIM cards and the lack of external storage. Then there's the question of availability (I had to go through quite a process to acquire a 32gb N5, and the Nexus phones are rather lacking in my country, which is going to make selling it fairly hard as there's literally zero advertising of those phones) and the price. Of course the price that is on Play in US is rather low, but the european version, and in a place where Play still doesn't operate, the price is pretty much that of other, more capable phones.
That said, while I'm not gonna buy a Nexus, I'm even more definitely not going to buy a Samsung. I hate the direction Samsung has taken. Their phones, while quite capable, look awful, lack real innovation (well, I'm not really part of their target audience I suppose) and are hardly customizable (trouble with new ROMs and stuff, from what I've heard). I'm probably going to go for an HTC or a Sony phone, but I will also closely monitor how is LG doing (I have an aversion to them but seeing as G2 and N5 are good phones I might just get convinced) and what's going to be with the next Motorola (the Google one).
