For the next 60 days you will have access to both versions, you just need to pay attention to with whichever version you want to open your files with - the newer version will NOT overwrite the older one - both will be available to you even the 60 days trial period. After 60 days the 2010 will stop functioning and will ask you to purchase it - just delete it (remove the whole suite via control panel) so it won't bloat your computer and run some register cleaner such is eusing to get rid of old files. (not mandatory but cleaning a registry every now and then, tends to improve the performance of your machine).
IMO 2010 Office sucks. Many add ons that work with 2003 do not work with 2010, so I too am sticking with 2003 - it's a too good of a program.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
