Synching your personal files and data between your PC and laptop (and maybe smartphone) is possible. Most of the time you want your devices synched with the most current data. So if you update a contact's info on your phone you get the new data synched with your PC and laptop.
But there can be some limitations, mostly based on exactly what data or files you want synched up.
I'm able to syn my iPhone with my Outlook files.
What I really need it the ability to work on my laptop having the same files as my PC while I'm traveling and not have to update the PC when I come home. Additionally, I need to have my laptop up to date so I can take it on the road and have all the same files as on my PC at home.
What do you suggest as the best method to achieving this need?
