" that is only 5.7 MB to download"
IE comes on computers...whats your point?
" has a better rendering engine,"
does it? i've never noticed a difference.
"an open SDK for third party add-ons (of which I use quite a few), "
and i dont use any. nice feature, not necessarily an improvement.
"and built in tabbed browsing"
which caused great annoyance to me until i figured out how to disable new tabs from openeing on a scroll wheel click.
it does have a built in spell check though, which is great. it makes the bugs and random crashing almost bearable.
