Changing to HTC Desire Z - thinking

I'm considering to change my android phone Sony Xperia X10 mini pro to HTC Desire Z. Sure I've just updated the firmware for this X10 and i liked the new updated stuffs. But there is still one drawback: the tiny fonts. At my age a larger font would go easier on my eyes especially since i do a lot of texting and mobile blogging. I couldn't find the font size adjustment in this Xperia and many of the rich text mail has extra tiny fonts. Fortunately the road sync has very nice comfortable fonts but it only allow one email account though. So my next best option is to plough in some dough perhaps trade in or sell my Xperia X10 and upgrade to HTC Desire Z. I know HTC got font sie adjustment base on my short lived experience of using HTC Wildfire. So it is just a matter of time for me to change my mobile phone.
