Axis performs admirably on iOS, and it's a great alternative to Safari on your iPhone or iPad. It can be rough around the edges during browsing (zooming and such), but I like how the search bar works, and the Google-like image browsing works very well. Adding and organizing bookmarks in Axis is on another level when compared to Safaris efforts in that area. The Axis designers have done an excellent job in giving each feature enough space on the screen if you want to browse while fiddling with things, but said features are presented exceptionally if you bring them to the forefront.
The desktop is a different story; While using it in conjunction with Axis iOS makes sharing bookmarks and other info effortless, the lack of a standalone product is odd, especially given the browser on iOS. Aside from sharing bookmarks, there's no other sort of value add here, so why not just use plain old Firefox or Chrome? Being on Apple products will help Axis gain steam, but unless you're a dedicated Yahoo user, this might not be very appealing. This is a compelling product, but I have a hard time believing that Google/Chrome fans are going to abandon ship.
So what happens after this article goes live? I'll be disabling the Axis plugin on my desktop, but the browser survives on my iPad. Safari is a very basic iPad/iOS browser, so using Axis and it's preferable UI and feature set in the near future is the obvious choice.
