worst product, well, theres lots that were bad that all kind of fit in that basket - ME would have to have caused me the most headaches handsdown though (what was I thinking using that on business workstation)...

quite a few far exceeded my expectations - such as qbasic (the free one that came with dos and began my career in app development when I was just a wee lad) and all their wireless keyboard/mice work awesomely for me even on just ONE battery! (still freaks me out how a device can work with a battery missing)...

Server 2003 SBS would have to be the best product I've had the joy to use, though those new VB.Express / SQL Express have really raised my eyebrows and might just take the win (and their FREE!)
