You aren't likely to convert any current tablet owner with a commercial. You can influence the customers who aren't married to any ecosystem or brand, though.
Of course you can convert any iPad owner who is eager to have a usable keyboard and a great Office suite on her tablet so she can stop carrying both a tablet and a laptop with her everywhere.
Office suite, sure, but keyboard? In both cases, a physical keyboard is an add-on that you buy, and the quality of the keyboard is pretty much up to you to decide then.
