The absence of a Micro SD slot is a bit odd for a GPS-equipped handset when so many navigation software packages come on memory cards and are sold under the premise of plug in and away you go. We have little doubt you could copy the data and applications across onto the Diamond to the same effect, but that's hardly the point. Some folk are just not that technically clued up, and besides, who wants to eat into their media storage with navigation software and maps?
With the Diamond, HTC has finally seen fit to move on from the rather lacklustre screens fitted to its other handsets. The 2.8in, 480 x 620, 65,536-colour job on the Diamond is bright, clear and easily readable in even the strongest sunlight, something you couldn't really say of the the screens on the other Touch family handsets.

When all is said and done, though, the Diamond is frankly less about what it does than how it does it. The big idea on this device is the TouchFlo 3D control interface, HTC's latest effort to keep its users beyond the clammy and odious grip of the underlying Windows Mobile UI.
It has done a pretty good job. What you have is a home page and nine other screens that swipe one to the next allowing you access to your contacts, texts, email, web browser, pictures and videos, music, the weather, settings and programs. Each screen shares a common background and comes with it's own rather funky graphics.
At the bottom of the screen sits a row of ten menu tabs, one for each screen though only five show at any one time. Below, sit two soft-menu buttons. Together, all these controls give you can access to most functions. The majority of subsidiary menus are rendered at a finger friendly scale so you have to drill pretty deep to come across those annoyingly small and fiddly Window's menus that require the stylus.
Though the home page's faux electric clock is a nice bit of design, it's the weather screen that is really TouchFlo 3D's poster child, with its clouds, rain and even a virtual windscreen wiper. Yes, the wiper's wholly pointless but we have yet to find anyone who wasn't at least slightly amused by it.

Who wants to know why Win Mobile = FAIL???
When the original HTC Touch was introed about a year ago, I bought one of the first 100 in the UK, no contract, and WINced at how much I paid. But the small size of it, and the apparent coolness factor, were enough for me to get over it.
Now I've had it for a year, and tomorrow night I am sitting in a camp chair in a queue for a new iPhone. I have HAD it with Windows Mobile - absolutely HAD it. Too many small fiddly menu choices that are IMPOSSIBLE to navigate with a finger tip, and many of them cascading! They put cascading menus on a MOBILE device with a finger touch screen?!?!? And that f£"$ing touch keyboard - I have small fingers, and loads of patience, but frankly I have to reach for the stylus for anything longer than one or two sentances, and even that is painful. And the number of times I have tried to punctuate a sentence and ended up bringing up the freakin' MENU instead I have lost count of!!!
I tried a 3G iPhone the other day, and was AMAZED at how much easier it was to use, type on, and navigate. The larger screen makes all of the screen functions MUCH easier to use - the menus are more logical and less fiddly, and the screen itself is just beautiful. I have a couple of Windows Mobile applications that I will miss (especially my Chess tutorial program), and the lack of stereo Bluetooth is criminal, but overall I think I can live without them just to get a phone that works. Now I just have to plan how to spent 12 hours in line tomorrow night...
And no, I've never owned an Apple product in my life, hardly a fanboi, but I have to hand it to Jobs on this one...
@Maryland, SCREEN SIZE FFS
The Diamond has a VGA 480x640 screen, and so it packs in twice as many pixels as the iPhone. That works out to an impressive 280dpi, and it looks fantastic.
Shame about the battery life, though.
got one - 7/10
I recently got given one for work and my personal phone is an iphone, so comparison is fair.
Funnily enough this seems the right combination. From an interface point of view I prefer the i-phone and the touch screen is far less fiddly than that of the Diamond, BUT....
What I want from a work phone is
1. Portability - diamond takes much much less pocket space
2. Functionality - Able to read and work on Microsoft docments a real plus without non-prop add ons. Also I do a lot of walking around strange towns (work related - please don't ask), so having GPS on board knocks my current 1.0 i-phone into a cocked hat
Personal opinion is they could have improved the touch screen interface, but otherwise a great little work phone. For a personal phone I would still go with the iphone though!
PS Biggest downside (which is not the phones fault) is the Norwegian OS I am stuck with - thanks procurement for that little gem.
Is the resolution really "480 x 620"?
If so, that would be 4X the normal QVGA offering (320 x 240) and probably more than anyone could use in a 2.8-inch display. If this is s typo, what's the true resolution?
@Neil Greatorex, others
Seriously, what's wrong with Windows Mobile? Apart from it being MS Software so "IT SUXXX COS BIL GATEZ WROTE IT LOLZ"? I bet it'd be a ninth wonder of the world (after Linus Torvalds and his mighty finnish brain) if it was "Linux Mobile".
It's not particularly hard to use- easier than other phones I've had, it has a massive amount of software available for it (and it's quick + easy to write new stuff for it w/ visual studio if there's something you need), and resetting once a week is hardly a hardship if you just do it at night- hit reset, stick on charger, fall asleep.
I follow this routine, and I've been using WM2003/WM5/WM6 for about 3 years on a few different handsets and apart from the occasionally badly cooked alpha-stage custom ROM I've randomly downloaded from the 'net, I've had no major software screw ups. The phone's only run out of battery power on me once and that was due to me losing it for a week with WiFi/BT/3G all turned on.
As far as slooooow OSs go, it's not slow for me. Maybe your network's bundled trillions useless, memory-eating apps with your version? IMHO, it's these that break and these that slow WM down to the horrible thing some people see.
WM6 rocks. Even on my newly-upgraded-to-WM6 2 or 3 year old XDA2s it rocks. Network added apps don't.
@"HTC FOR THE FAIL"AC, it's called a Crackberry as everyone who has one- especially those who use it as a verb (as in "Blackberry me")- are arses.
