My trusty Galaxy Nexus has been by far one of my most beloved phones : I loved the design, the openess and the available development (custom ROMs). It has been running ParanoidAndroid most of the time, but when KitKat wasn't available anymore for the GNex, and because PA4 just sucked, I switched to Shiny ROM during its last months.
However, the internal storage was way too low (16GB), way too slow, and the battery was mediocre to say at least. So end of July, I started looking around for a replacement. Initially, I planned on waiting untill the Nexus6 would be available, but rumours about its 6 inch screen did me fear that its price tag would be also impressive.
My eye fell on the Oneplus One, and despite the questions about Oneplus' ability to support, I decided end July to bite the bullet, and to purchase a OnePlus One. An invite was easily found on G+, and beginning of August, I got the phone in the mail. Impressive by size, this phone is located deep into phablet territory. However, its size quickly gets used to. I wasn't really impressed with the sandstone back, I even feared it would be too fragile and damage prone, but after 5 months, it proves to be quite durable. I'm not so wild of the design either, I would have like some more rounded corners.
But apart from that, my experience of the phone has been allround positive : the phone is fast thanks to the Snapdragon 801, and 3GB of memory, and the 64GB of storage is a bliss. The battery covers mostly 2 days even with moderate to heavy use. Add Cyanogemod on the software side, combined with Exposed Framework, and count me as a happy man.
