The slide-out keyboard and tilting screen make the TyTN II an exremely easy to use and productive email tool. For someone like myself who's out and about and needs to respond to emails about work and new products, it's an invaluable tool. My first impressions of the keyboard were that it was good, but not as good as the Toshiba G900's. I'm still of that opinion, but as time goes by I'm getting more and more comfortable with it, and tapping out emails is now even more of a quick and hassle-free process.
The build quality is still a revelation. With such a complex mechanism behind the sliding keyboard, you might expect the hinge to give a little, but not a bit of it. Both the TyTN II's I've seen have been rock solid, and make a pleasing thunk whenever you slide the keyboard out. It's also quite remarkable that HTC has been able to squeeze this into a chassis that, while it could not be described as slim or light at 19mm thick and 190g in weight, is certainly more pocketable than many less well-featured smart phones on the market today.
Now that I've had a second look at it I can confirm that the positioning of the clickable scroll wheel on the left of the device is truly a work of genius. Not only does it fall under the thumb neatly when you've got it in phone mode, but once you slide the keyboard out and hold the TyTN II in two hands, it falls directly under your right index finger, which makes navigating through my huge contacts list an absolute doddle.
The fact that it'll connect to just about anything you can think of is a massive bonus. My working arrangements involve working at home and in an office at the moment, and the Wi-Fi connection really comes into its own here, allowing me to sync over the air without it costing the earth in data costs. I've also got Skype installed on it, which enables me to take advantage of cheap/free calls when I'm at home without eating into my valuable mobile tariff.
