Chrome continues to improve technically. Very impressive. I don't get why its usability pales in comparison. Firefox leads by a significant margin in this area. Too many things that I do repeatedly are less convenient, more annoying, or simply impossible in Chrome.
* Can't use tab key to select items in the URL combo box -- it's necessary to move hand to use arrow keys. Stupid.
* Can't use middle mouse button to open a new tab for everything. In Firefox I can do this from the Back button menu and almost everywhere else. I use this constantly.
* Back and forward buttons require that you hold them to get the menu. I hate this. Again, Firefox's solution is much faster and more responsive.
* Simplicity? More like lack of customization.
But damn, it is fast and technically impressive.
