I bought the OnePlus One in january first week this year. It has been about 10 months and I am loving it!
High end specs, low price point sweetened the deal. All apps, games etc run without a lag thanks to the SnapDragon 801 chip and 3GB RAM. The Camera is good but the lack of OIS is felt in more than one application!
The 4K recording is a feature which did make this device unique and yea! it consumes a lot of storage. The 64GB internal memory does the job for most of the storage needs. 4G LTE though only in few places is quite handy!
Overall this phone is a killer piece of tech in hands!
