On a physical keyboard, we can rest our fingers on it without actually pressing anything. On a touchscreen interface however any finger touch will be registered as a key-press. Verdict: Keyboard , touchscreen  (keyboard wins).
Some statistics suggested that people who do lots of typing are more prone to RSI injury as compared to people who use mouse more.

I still think that cloud computing is a stupid idea, unless the hi-speed internet access is to be made free of all costs at a much wider coverage by multiple folds than the current state in conjunction with the implementation of the technology, and provided that I can still work on my files offline in local machines. I’m not anti technology, just pointing out the practicality.
