windows 8 facebook and amazon apps

i'm using windows 8 on an old laptop and i just can't believe how much it feels like a brand new computer (i already ranted about some aspects of win8 i don't like but some things are great). so i wanted to download a facebook app from the ms store. i don't think the people tile is good enough. then i remembered that the people tile opened up facebook in ie 10 which looked phenominal. i decided to pin my facebook home page to my start screen. i now decided to get rid of the people tile. ie 10 is so fast and beautiful it's easier and better to just pin fb to the home page. same with amazon and ebay. any thoughts on if this is going to be the case on the new windows phones? or do you think apps are going to be needed for functionality?
