I'm weird, but my main requirement in a client is that I never miss anything. That means remembering my positions in each timeline and paginating correctly. There's only one client for Android that I'm aware of that does this - #AndStatus. Until recently, anyway. About a month ago it started forgetting media, jumping position on sync, and today I discovered the combined view for multiple instances gets confused and leaves hours-long gaps in my home timelines. So now there are zero.
