I have recently begin to feel the wrath of the infamous Carpal tunnel syndrome -lrb- kind of know it be come ... be just a matter of time -rrb- from extensive code and overall computer usage . thanks to CTS , I be not able to use conventional keyboard . as a result , I decide to purchase this keyboard . when I be at staple , I like the schematic and the way it feel to my hand . nevertheless , I be a bit skeptical ... after all , it be design and manufacture by Microsoft and I be not a Microsoft fan . since I buy it this evening , I have already use it for about four hour and I must say that I love this product ! I never feel this comfortable and free of pain . the cramp and strain I would occasionally experience while typing be no longer there ! this be probably the best product Microsoft have come up with after Windows NT ! if you be a computer science\/systems\/networking student or even a professional programmer\/systems and or network administrator , do not make the same mistake I do . get this keyboard before it be too late . it 'll pay off in the longer run . but if you end up like I , you will end up have to pay in many different way ... not just financially .
