Haha. At last!
Linux only has less service packs because its releases are service packs. If you get Windows XP SP2 on CD; that's what its like getting a new Linux - every new release is a new service pack. Windows makes a point of becoming vastly superior in every release. Have you not wondered why there are Linux Versions 5.9.7.283.912.732.1283 - they're service packed - they just don't release them for patching all the time like Microsoft do.
Haha; missed a whole page there!
Yeah; being Open-Source if Linux was in the position Windows is in it would be twice, three times as insecure as Windows is now. There isn't the tech, or the money, or the organisation from a non-profit non-centralised organisation to produce the stuff and power needed to keep everybody updated for free like Windows does. There would be no free support, no free updates. At best you could download a new version and install it but you'd have to pay for the CD to be sent if you know nothing, or for a tech-guy to come over and install it afterwards even if you download it. For most people; Linux is no possible, not only because of the dreadful uselessness of the Programming Model but because of the drastic security concerns involved with allowing people to edit Operating Systems in ways that few could notice and then sell them on to the public legally, who would have no idea of the changes made which could send pictures to the person, or files, or personal details, or e-mails and addresses.
