Try using the smartcover in portrait mode. I have one and you can't, but you can use alternate cases just like you can with the Surface. Widescreen tablets are based around landscape use and this has nothing to do with the kickstand or keyboard cover.
Of course a salesperson is going to push the keyboard cover, duh. Its an accessory, and accessories have high profit margins.
The Surface RT is the same price as the iPad 4.
But, the smartcover for the iPad is an accessory as well, and there is not a kickstand for the iPad, which points to its more flexible design. If you want to use the Surface in portrait mode, it is just not a pleasant experience.
As for the Surface RT price, you pay the same as you would for an iPad 4 (for the same amount of storage, by the way). Yes. That's exactly why I cannot see how anyone would want it. Go Android (if we are talking about Apple alternatives) and you get an arguably better device (the Nexus 10) for $100 less. LOL. The Surface is overpriced and underperforms, not to mention the poor design choices I have already mentioned.
