No worries Toyface! I've had the TPU case for a week now and have already taken it on a business trip with me. I find it unobtrusive and very comfortable to hold in one hand, with the grippy texture on the back. The volume and power buttons are not tougher to use at all. I've even gotten used to the fingerprints on the shiny parts. The ONLY downside is that on some of the USB plugs I've used since the video, some of them do deform the rubber on the lip a little. I doubt this will be a long term issue though, it springs right back when I unplug it.
On real-life bumps: when the tablet slid off of a chair during an airplane landing (my bad, it was sitting on my coat and fell off as the plane was braking), it landed face down and had no damage. Incidentally, my headphone jack was plugged in and while the jack was bent, the tablet was undamaged and kept working with the earphones. Point LG!
Finally, when I carry this thing around outside, I use a slipcase for an old Acer netbook. Not the most ideal shape, and I may get a more form-fitting one eventually, but it works. It's to the point where I may not get the IVSO / generic flip case after all, as this is working just fine for me.
Please post some pics of your red version when you get it!
