I've always found uptime to be useful for my servers, mainly because they actually do things that require it. But to have a featureless, unsupported and overall useless communication device that cannot surf any modern websites or communicate using more popular platforms with actual people that use those popular platforms is the key difference.

Simply stated, and I really do not want a semantic battle over what comes next - I want a communication device that can interface what my needs are today and not what they were in 2008. I want a device that actually has little to no noticeable lag in the times I really find it frustrating and can do what I need. Uptime is at the lowest of the things that I'm looking for to be honest - stability is great, but if it cannot interface a damn thing, uptime just means that I'm in possession of a device that does nothing but give me bragging rights.

tl;dr **** uptime. Give me functions.
