Yep! E71, E72, and E6 were some of my most loved phones. My love of that form factor meant that my first foray into Android was the HTC ChaCha - that was a mistake.
It was slow and buggy, but it felt like a handheld computer.
Qtek rebranded to HTC and I bought a HTC Touch running Windows Mobile 6.0, I am not sure when or what I switched to afterwards, maybe an Android.
