I tried it and think I'm going to use it instead of the Safari browser. Initially I didn't like the small rendering of text when a page loads at first. But then I realized it was actually more efficient at zooming in and out by simply touching the area you want to read, instead of having to pinch it in and out. Very cool.
Plus it rendered the sections of the pages way more readable than Safari.
The tabbed browsing is awesome. The speed was killer. And I love how it does not refresh a page automatically when you jump from tab to tab. That annoyed me so much on Safari, since it would take 10-20 seconds sometimes to reload a page just when you wanted tab back to it.
No problem with forms here. I use forms to edit pages on my site(s). Worked great.
Nice first cut. Looking forward to using it more.
