See, I had one as well. I always had proper belt cases on my phones, so I never experienced any butt dialling or back cover issues. The keyboard lock was annoying for sure.
I always loved the weight and size of that phone generation. I’ve got giant hands and later phones just felt too small to comfortably use. Heck, I’d buy one of those giant brick phones if they sold a decent one. Give me that two week battery life!
