IBrowse is nothing like AWeb, it's quite good actually. I use it to post here, to check out news and to do my online banking. Having said that, it's not a cure-all browser. It can't do CSS and flash yet. It's fast and very stable (since I bought it in the beginning of the year, it's crashed on me twice, I think) and it renders quite alot of pages well. It's one of the best purchases I have done ever for my amiga.
It has tabbed browsing, as you may have seen on Opera and Mozilla and much more. We'll see, next version might be a solve-all release, who knows?
