I've found this thread to be really helpful.  I'm in a similar situation to Tonio.  I want a phone that I can use occasionally for business.  I want to be able to pick up emails and have access to downloaded MS Word or Excel documents.  I dislike regular phones as they are almost impossible to enter reasonable amounts of data/text into, so that pushes me towards the keyboard sort of phone.  However, they always seem so big compared to a normal phone.  I had an O2 Xda thing a couple of years ago and hated it because of it's unwieldy size.  Are the new generation of Blackberry or HTC phones a bit smaller than the old Xda?
 I really like my Sony Ericsson W880i as it is so small, slim and light.  I hardly notice it when it's in the inside pocket in my leathers.  As a phone it's great as the battery life is excellent.  As a pseudo business tool though it's useless.
 I'm torn betwen the full-on busienss type phone like the HTC Pro, the Blackberry, Nokia N95 etc or going for something without a keyboard such as the HTC Diamond.
 Has anyone got any experience of the non-keyboard type like the Diamond?  Are they still ok to enter text into or do I really need a keyboard?  I don't enter much data/text, but then I find sending normal text messages to be a real slow affair anyway.
 I want something which is primarily a phone, and small and light, but I also want to be able to look at spreadsheets and documents, have my Outlook contacts and calendar synced up from my stand-alone PC, and be easy to enter text into.  I'm not a corporate animal and don't need to have video conference calls with 6 people from around the globe.  What should I be looking at?
 I see that HTC have launched a couple of new models too which look really good.
