The first time you see your ax in all its glory, I envy you. Hit
www.freewareppc.com and install like a madman, also check out handango and go crazy with the trials. Keep seperate folders for apps you like and those you don't once you think you have what you want do a hard reset and re-install the apps you like that should last you a few months; until of course you have tried out and uninstalled other stuff and it gets cluttered.
Just remember once you satisified with your apps. run the backup through ActiveSynch (save the file somewhere safe)
