Beat me to it, yes they have been around years, and it is a sds drill, but also has a torque adjustable clutch for use as a screwdriver. I believe no other company has such a system, and its ideally suited for use up ladders and roofs for example satalite and aerial installers as they can do the job with only one drill.
Other manufactures (i know dewalt, hitachi, and makita) have had 'C' type drills in the past but tht 'T' shape has completely taken over.
I have had a T18, and a protool PDC for years, and have just recently got a C18 and a CXS.
I CXS feels the best now, even after years of 'T' shape drill use, but the C18 i find little bit odd still, because on the cxs the trigger is small and i use my middle finger, but on the the c18 the trigger is much larger and you really need two fingers to operate the switch but find it unnatural to use my middle finger on this drill when ime fine on the cxs and hence is my now favourite drill especially for screwdriving.
