too many bugs... not worth the dL (i just downgraded back to 4.7) but I did like the tab browsing, browser ran a little faster by 10 seconds less than 4.7 I didn't like the media icon (it was separated from the pics, ringtones, voice recorder, and videos-- they were all the same) no lag in sending email or sms. I like the separate file folders and thats about it. Some applications didn't work or was recognized. I'm going to wait for the official release.
