Just got my i5 sp3 yesterday. Picking it up from best buy today. They kept it overnight to install updates, antivirus, office, etc. First question - is there anything they wouldn't install normally that I should have them install when I pick up? Thinking Intel drivers and the like. Second question - I chose i5 over i7 and don't want to regret it. I just think i7 isn't necessary for my usage. This is a business machine (word, outlook, excel, calendars) that will be used as a tablet for movies, music, browsing at home at night. My video game playing is minimal and if I wanted a device for games I'd do a monster desktop. Mi don't do graphic design or anything creative like that at all. But I must have switching fast between applications and I hate lag. Third question - what are some of the "must have" apps available right now that I should pick up immediately? Fourth question - I bought a protective bag, wireless mouse, and type cover. Any hardware I'm going to want that I left behind? Thanks all.
