The smartphone that I allways remember missing the most is the Nokia E7, it was such a cool phone.
The design is beautiful, the physical keyboard was amazing, sure Symbian wasn’t the fastest or the most modern OS, but with Anna and later Belle it worked well.
I remember sitting in the lobby of a hospital with my E7, I ran Putty Touch on it and was connected to my friend’s SSH server, and had connected to my irssi screen session, I had configured touch gestures to scroll in the IRC chat and to switch irssi windows based on if I swiped up/down or left/right, the physical qwerty keyboard made the phone look like a tiny laptop, and I felt like such a hacker.
I was working a job I hated, but on the way home I would watch movies on the phone, and it worked so well.
It was an awesome phone, and someone else thought so too and it was pickpocketed, a year after I got it.
