Google's Chrome browser has been chewing up market share on desktops and laptops for a while now, and now they're going mobile. If you've got an Android 4.0 (Ice Cream Sandwich) phone or tablet you can download it now, and it's a BIG step forward.
There are a lot of new features, but the banner one has got to be automatic tab and bookmark syncing between your desktop and phone. So you've got a few tabs open at home, and have to run out the door? Not a problem, you've got those same tabs open on your phone already. It's also just a much slicker UI. It borrows a lot of the swiping gestures that are deeply integrated in Ice Cream Sandwich for easier and more intuitive navigation. Tab-management looks awesome, and early indications seem like it's more than fast enough (quicker than the already fast Android 4.0 stock browser).
Will update shortly with hands-on impressions.
UPDATE: Just spent some hands on time with Chrome Beta on a Galaxy Nexus. Here are my quick notes:
It looks really, really good. Tab management is fantastic. Either swiping from one side of the screen to the other to switch, or by using the card viewer, it's fast and intuitive. Websites usually tired to reload when I went back into the tab, which slowed things down and was pretty annoying. Scrolling on pages was very fast in general, as was zooming in and out.
Syncing it up with my desktop Chrome browser was really easy, and within minute I had access to all of the tabs I opened (though it seemed to only show the ones I opened going forward, but not the ones that were open before I linked it all up).
The biggest, saddest omission is that it is lacking the "Request desktop site" button that you find in the stock Android 4.0 browser, which allows you to view a full site instead of the mobile version. That's one of my favorite features from Android 4.0's browser, and it's a drag to find it missing here, but hopefully that will be coming soon.
Over all, it's fast and pretty and considering it's in Beta, it's in pretty good shape. Hopefully it will only improve from here.
