Ok, now that I’ve calmed down, I’ve rationalized the problem, and it is a huge problem, that any competent reviewers should have recognized quite quickly, why they didn't is beyond me.
Here’s the real problem.
1st we have to understand that this unit is both a PDA and a Phone, and that they're not really merged together, rather are still very separate units within the same unit, kind of like two half’s of a brain.
2nd the Bluetooth hardware and software in this unit is completely controlled by the PDA part of the unit.
So when our PDA part of our units are turned off, we leave the Phone Part of our units on. At this stage there is no working Bluetooth connection. Why? because its controlled by the PDA part of the unit, which is off. This results in
a number of problems.
1- if when you receive a call, the PDA part of the unit wakes up, BUT it has to re-initialize the Bluetooth connection, a process that takes at least 45 seconds, if it actually works, which it doesn't for most of the time.
2- another problem, related to the 1st is that Bluetooth doesn't really have the ability to re-initialize, so basically, if you want the Bluetooth to behave with any predictability/reliability, you have to turn the connection OFF every time you turn off the PDA, and turn the connection ON & connect to a device, every time you want to use the Bluetooth. Obviously, in the end this is extremely inconvenient - "ah, ya, could you hold on for minute while, i start my Bluetooth up, and then get it to connect to my..." ever time you have a call, not to mention the inconvenience of having to remember to turn off the Bluetooth, every time you turn of the PDA part of the unit.
NOW to drive home the problem, we compar this to a Proper Cell phone with Bluetooth capabilities (hereinafter BlueCell).
On a BlueCell, all you have to do is turn your phone on, then go through the bluetooth connection procedure to link it to the headset. Then your set for the rest of the week, until either your headset or your phone battery dies. There is no real connection problems, because your Cell, which controls the Bluetooth, stays on, all the time, so there are no re-connection problems,,etc.. the process works relatively flawless.
SO if HP, or what ever company really designed this unit, had there act together they would have assigned the bluetooth hardware to teh Phone Part of the Unit, and NOT the PDA part of the unit, because in reality 90% of the users of this unit in North America will be using Bluetooth with a headset, and not with a modem, or printer..etc(which would require the bluetooth to be controlled by the PDA part of the unit). And really this Unit is not really capable of true phone duty, in and of itself, with out the use of a headset, because of the shier size, shape and weight of the unit. On a side note, this really is a problem that was created by a lack of understand/communication between the enginears who designed the units hardware with those that designed the units software (aka micros**t) - basicaly thinking that the OS bluetooth software could accomodate the needs of the phone's bluetooth needs, which for reasons i've mentioned above, it can't. Or then again, maybe they knew, possibly even planned - ensuring for future production model improvments
In the end, contrary to all the bs hype out there, this unit is completely NOT suitable for a real business professional, as it does not replace the need for a good cell phone. You can use this thing for light phone duty and personal calls, but there's absolutely no way i can use this thing for business, so really in the end really all I really have is a large, ungainly, slow PDA, albeit with excellent battery power, which i suppose is, inadvertently, is only saving grace.
Here how i would have rated this Unit for a business professional:
Pros:
*Capable of very light phone duty (true world phone - not that it matters)
* excellent battery power - its only real saving grace
* Full gamit of wireless capabilities
* Adequate processing power for business applications - unit was responsive enough for everyday use.
Cons:
* Heavy
* Ungainly - thick, and aerial numb.
* Slow (may not be a problem depending on what you intend to use if for
* No real Bluetooth phone capabilities, contrary to what they would have you believe.
* even if you use it as a phone, the ringer volume is pathetic
Rating: 6./10
Assuming you've read this far (big assumption

)Would higly suggest for those of you that really need to use your cell phone a lot, that you not consider this unit a replacement for it, cause its not. So this may not be the unit for you, might be better off locking at a treo or just getting a light, thin PDA, and a good bluetooth phone and headset. As a PDA, basically there are lighter, cheaper, better units on the market
enough said?
