Well, I just went ahead and bought it--figured I would just be out a buck if it didn't work. Made a huge diff in Chrome's Sunspider scores- 4X faster overall! Apps like Facebook, CNN and Flipboard seem to be loading content noticeably faster. Haven't found any downsides so far.
I bought it the MINUTE I read the description and loved it. Version 1.0.1 was causing me to respring into safemode, but the support from the developer was amazing! He emailed me beta deb files, took my crash logs, even offered me a refund with no problem. I decided to stick it out and waited for an update, took him a couple of hours to push it through and my phone works fine now. Have no complaints and facebook loads content lag free. Chrome as well.
but how is safari tho? i do not care about any other browser
I bought it for use with my other programs (facebook, etc) since I use a lot of apps that access the web. It works well. There is a distinct difference that i've seen in performance so I can't complain.
