I use chrome and it is set to my default browser (jailbreak). The only thing I want is Safari Download Manager ported over to Chrome. And maybe a hack to run Nitro in UIWebView, but that would just be the creaming on an otherwise good cake.
I don't care about bookmarks on my iOS devices, but I do find it eligant and fast to access my bookmarks on my Chrome work computer, or private home laptop. (open a new tab anyway, bookmarks -> bookmarsk -> choose computer)
The Other devices tab function, i use all the time, to work seamless across my devices.
Cant wait to see other tweaks appear in cydia for Chrome, the only I fancy as of yet is to change default browser. But I'm hoping for more
