I remember reading one poster's opinion, in one of the long threads, that the matte was NOT less slippery, but I'm interested in getting additional opinions before possibly ordering. 'Cuz I'm loving the glossy black Ultra Thin but it slips right out of my hand (or pocket or purse) ALL THE TIME. This hasn't happened with any other case I've tried. I did try the Incase Snap soft touch, but it didn't fit right (with only front screen protector) and it felt not nearly as refined as the SGP. The more rounded edges of the SGP, the cool side button cutouts, the amazing fit and the slightly better lay-on-the-table-ness just make it feel so much better than the Incase did, to me. I could live without the logo cutout on the back, but it's not a deal breaker. So.....try the matte version of the Ultra Thin?? Or keep looking??
