The limitations are not really a problem for me. If you're referring to the sporadic datastore errors, that was actually resolved in 1.3.1, by having it auto-retry natively (no need for a decorator anymore). I would really like to see support for 500 MB files in GAE, so I don't need to use S3 anymore (large game downloads). Comet support would also be fantastic. I'd also like to see lower latency. However, these are not deal breakers for me and I am more than satisfied with GAE. I am tracking maybe seven issues on the Google Code issues list, and if those were fixed, I seriously would not have any gripes about the service.
