More impressive is the set of icons that appear when you dial your Next G voicemail box. Styled like the controls on a VCR or CD player they make fast work on playing, deleting, skipping over and saving messages with a tap of the stylus, instead of having to remember numbers on the keypad.
For all that, the interface is littered with some confusing references. The Today screen itself has a Messages field for accessing email and Text Messages for SMS and MMS, while the Start menu lists the Inbox for email (handled via the standard Outlook Mobile client) and Messaging for running the SMS/MMS client.
Other Treo tweaks include the ability to ignore an incoming call but send an SMS in response (pick a message from the supplied list or roll your own in advance), and listing all contacts numbers for a missed call made by someone in your address book rather than just the number they dialled in on.
Everything else on the Treo 750's checklist is largely par for the Windows Mobile PDA/smartphone course, including edit capabilities for Office documents due to its use of the Pocket PC Phone Edition of Windows Mobile 5. This includes out of the box support for push email via Exchange through Microsoft's Messaging and Feature Pack.
Extra applications include the Picsel PDF viewer (pre-loaded in ROM), a full version of Microsoft's surprisingly effective Voice Command software (which usually sells for US$40) and a chat-style SMS application which shows successive messages in an SMS session as if they were a chat or IM conversation rather than a series of stand-alone messages.
Performance
With so many capabilities on tap and such an impressive array of tech crammed under the hood, the Treo 750 has been shortchanged in the CPU department.
The powerplant is a 300MHz Samsung processor, which allegedly consumes less power than the closest Intel equivalent due to Samsung's use of separate memory chips. But 300MHz just isn't enough to do a decent job on a Windows Mobile smartphone, not when competitors are in the 400MHz weight class.
The Treo 680 used Intel's 312MHz PXA270 XScale chip to decent effect, but that was for an OS which remains almost unchanged after several years compared to the heavyweight Windows Mobile 5. Toss in the processing demands of mobile broadband and streaming video and there's no avoiding the fact that while the Treo 750 isn't a slow awkward stumbler, it needs (and deserves) more muscle under the hood.
Memory gets a better deal, with 64MB in RAM and 128MB of Flash ROM, 60MB of which is available to the user.
For heading online the Treo 750 can choose between the Next G (which it lists as 3G) and the EDGE-enhanced GSM networks, with users able to set which network is given first shot at connecting.
Online performance is as you'd expect from a device of this type. The HSDPA 1.8Mbps radio works in its favour to deliver true mobile broadband, although the bundled bonsai version of Internet Explorer is outclassed by Opera Mobile 3.
We experienced better results by press-ganging the Treo 750 into use as a wireless modem with a Bluetooth connection (USB and infra-red are also available) to a notebook PC, where we clocked a consistent 1.2Mbps signal around the CBD and North Sydney.
Directly available on the Treo 750 is Next G's portfolio of Foxtel Mobile channels. These include Sky News Headlines, Sky News Business, CNN and Fox Sports plus a selection of entertainment and children's channels.
When at their peak the media streams flowed fast and smooth, with quick buffering to begin playback. During our tests the video performance proved quite sporadic and journeyed from super-fast streams to stuttervision and near total breakup, especially when attempting to watch music video clips on the BigPond Music service.
As thin as the audio sounded, volume levels were sufficient for personal use (either for streaming content or playing music or video on the inbuilt Windows Media Player 10 Mobile) but bring the headphones if you want to step outdoors.
Palm rates the Treo 750's 1200mAH battery as being good for 4.5 hours of talk time and 10 days on standby. We'd tend towards the skinny side of those numbers if you get hooked on HSDPA, and suggest it'd be wise to keep the Treo topped up with a nightly recharge.
Editor's note: The Palm Treo 750 is expected to be available through networks other than Telstra mid-March.

What version of voice command does it use - this is important as only 1.6 uses bluetooth whereas 1.5 can only use the cabled headsets.
