Whether it's tick data, or bar data, it makes sense to have tools to summarize the data at lower frequency. Collecting 5s real time bars in IB, I'd often down-sample to 1min.
Tick data has its use, debugging comes to mind, but beyond that it's a waste of time, space and resources for anyone but HFTs.
