Yes, cold start (the delay you experience when your code hasn't been used in a while) is a big issue - it means serious additional latency which makes Lambda difficult to use for end-user facing applications. You can get around this by calling the code periodically .. but that defeats the purpose. There are also restrictions around how long your code can run. BUT, if your use case fits within these constraints, it's pretty cool to just deploy your code and forget about all of the administration hassles associated with running it on a server.
