the interface may be quite different, such as it’s method of presenting bookmarks, but the web would look almost exactly the same in the two.

in my opinion:

pros – much faster javascript vm means faster web apps (to google’s great delight), smaller memory footprint means it should stall less and let you do other things in the background, multi-threading means that tabs/windows don’t interfere and crash the entire thing (though i’d wonder how it would behave with lots of tabs and hence a large number of threads to manage – would you not see any benefit on a single core processor?)

cons – i dislike the look, i’m too used to having a bookmark bar always available, i’ve heard strange things about the t&cs (you allow them to spy on everything you type? something like that), what’s the point of it anyway (other than to use their brand image to drive people away from ie)? if it’s primarily to increase the speed of their web apps, why not help incorporate their vm into safari or firefox?

i’m slightly surprised that the various google apps are not bookmarked or linked to from their home page. every other browser does that to promote it’s websites and affiliates…
