Pretty sure the majority of people on this site would agree with you, but you gotta realize within the scope of windows laptops/convertables/etc, you're in the extreme minority. From a different perspective, I doubt there's many people out there that can type faster and more accurately on an SP3 typecover compared to a conventional keyboard. Its plus's are that it's light, while a traditional laptop keyboard wins in every other category. Not to say you can't be efficient with a typecover, just that you're less efficient than on a real keyboard - you can probably come close with enough practise though.
I've been beating this dead horse for awhile now though - everyone's got there own opinions, pretty much impossible to change those opinions once people have their bias's set.
