Max, are you a joke account?
4 weeks ending January 25th 2008.
Total SW sales: ~ 20M
Average SW weekly: 5M
47 weeks ending 28th November 2008
Total SW sales: 405M
Average SW weekly: 8.6M
I checked, the difference is bigger for 2007.
Hardware:
4 weeks ending 25th January: 6.5M
Average weekly: 1.63M
47 weeks ending 28th November 2008: 79.4M
Average weekly: 1.68M
So for hardware, January is almost exactly as big as the rest of the year. No real difference.
For software, January is a fair amount smaller than the rest of the year, simply because people have relatively lately been buying a lot of SW, and doesn't feel like buying a lot more.
I really hope I am misunderstanding what you say, because otherwise you have no point whatsoever.
PS: When you have data, write what the data is for. Otherwise, it makes no sense to anyone but you, and we cannot disprove your data.
