There are loads more things on the HTC Desire Z we're looking forward to testing - how does the screen look in bright light? What's the call quality like? Does filling it with content cause the 800MHz processor to slow down?

More importantly - does the 1300mAh battery stand up to the task of all day use when the HTC Legend and Desire failed so miserably?

But these are all questions for the forthcoming full and in-depth HTC Desire Z review, where we can properly probe the limits of this handset.

For now, we're quietly impressed with this QWERTY slider, as it offers a lot in a small package and doesn't fall down in areas other smartphones inexplicably manage to time after time - so despite the hype surrounding the HTC Desire HD, the HTC Desire Z seems to be an equally impressive phone too.
