i downloaded it, and it's more customizable on install. it features the install proggy that IE has been on since version 4. by customizable, i mean, i opted only to install the browser =)
it's interface is "slick" but it feels the same as 4.7 which is what i have installed. and uses themes...
it seems to be faster than 4.7 as far as i can "feel"
it's a real option for those who don't like ie.
but for those who don't care, like me, ie5.01 sp1 is fine for me ;-)
the inclusion of a java2 plugin rocks =) since that's what i am learning in comp sci, and i can use it for my applets =) though most of what i wrote are not applets
