Ok so I have been using my HTC Desire Z for about a month now and I have done a number of comparisons agains other smartphones and all I have to say is this is how smartphones should be.
Funcionality: This phone has some very cool features, the keyboard is brilliant, it has a nice 5mp camera with a flash which can also seperatly be used as a torch - very handy. The camera will also record 720p HD video and the frame rate is very impressive. It has a good quality lense too so the still pics are sharp, crisp and very detailed.
Ease of use: Its very easy to use, the built in keyboard makes it even easier. As a matter of fact, i am typing this review up on my Desire Z as we speak! Web pages are easier to browse and access than any other device ive used, except for my laptop/pc. With the use of Flash 10.1 you can now view almost any web page you want and view all its content from YouTube to BBC iPlayer which is great!
Styling: Personally, I think this phone has the looks. Its no thicker than an iPhone 4, no bigger either and the titanuim shell which surrounds its screen and covers the battery makes it look the part. Aside from the dedicated camera button, the volume buttons on the other side and the 'track pad' this phone has no other visible buttons, until you open up the keyboard. This gives it the look of something very serious and hi-tech. I will say however that this phone is a little weighty, its definitely something you can feel in your pocket. Some people may not like this, I do however. I like being able to feel my phone in my poket, I get worried if i can't!
Ok so to sum this phone up - it looks beautiful, has a good battery life and will do everything an iPhone will do, and more. Lots more. This is definitely a phone for people who want something more than just a fancy looking device than can send/recieve calls/texts and can browse the internet. This is a device which keep you entertained, occupied, and connected to everyone - everywhere. Its brilliant!
