i use it daily! I'm a home health nurse and spend a lot of time in my car. I use siri to bring up phone numbers, texting and map info on a regular basis. It's not without its hiccups, but hits much more often than misses!
can't even tell you the last time i used an optical drive. even the best imac speakers have been ok at best. there are excellent speakers out there that take up little desk space and produce very good sound. eliminating little used features, think floppy disk, makes room for far better tech. on the inside!
