Is it worth the upgrade? I'm currently using a Nexus 5 with a busted vibration motor that I think I've fixed buy, erm smashing it against my desk until it works... Anyway is the OPO upgraded worth it now Android L is just around the corner and I'll have to wait 3months for the upgrade on that phone? High rez audio decoding alone makes it seem worth the upgrade for £269 but browsing the r/oneplus subreddit makes me worried as it's full of people complaining about issues.
I have a Nexus 5 running the android L dev preview. I recommend you switch to the new android L and try it on your Nexus 5 before deciding to switch.
Yeah the new preview is great
