For technical reasons, I have to impose an article limit in Instapaper Pro 1.4 in addition to the new limit in Free. The iPhone doesn’t have enough horsepower and memory to hold more than a few hundred articles without massive complexity (and slowdowns) to load and unload subsets of them as you scroll.
For Instapaper Pro, I was thinking of a limit of 250. Would that be sufficient? I feel that it’s still a bit high for performance and stability, but I don’t want to frustrate Pro users if they really want that many. What limit would you propose?
