The Dell Axim x51v is one of the first Windows Mobile 5 devices in broad market release.  As with anything in computers that is the first of its breed, there are a few kinks that are still being worked out.  Readers may have seen comments to this affect after the previous parts of this review.  Dell has released a ROM update for this device that addresses some of the issues reported by x51v users.  But the update is getting mixed reviews.  In this final part of our Axim x51v In-Depth review, pdaBuzzers get a look at some of the issues with this device and whether Dell's latest ROM update provides a fix for them.

Software Glitches and Conflicts

One of the first issues reported by x51v users was disappearing memory cards.  Both Secure Digital and Compact Flash cards would disappear from the file system after a period of normal use.  Usually a performing a soft reset or removing and replacing the memory card resolved the issue.

Second and possibly related, users have reported that the x51v will intermittently not power up after being left in a standby state for a time.  A soft reset is required to get the device to turn on again.  Users have seen this when a memory card has been in one of the slots.  Sometimes, in addition to the device not turning on, the device will feel warm which has been due to the processor running at a high speed for apparently no reason.  If the Axim gets into this state for too long without being noticed, the battery will completely drain.

Many users have reported what they're calling the "White Screen of Death".  This is where the x51v is placed in the cradle to sync, but instead of coming on and syncing the device's screen turns on and displays and all-white screen instead.  A soft reset is again required to bring the device back to a usable state.

Nearly all Bluetooth users have reported that the included Microsoft Bluetooth stack is a big step backward in functionality.  Many have reported not being able to connect to their phones, headsets, etc.  Users were looking to the upcoming Dell ROM update to receive a more functional Bluetooth implementation.

The Dell Axim v51v ROM Version A04

Most x51v's shipped with ROM version A00 or A01.  Mine came with A01 and I personally experienced several of the frustrating issues listed above.  So I was pleased when news broke early last week that Dell had issued an update for the device.  After syncing all essential data with my desktop I applied the update. 

One important side note here:  Do not depend on the backup functionality built into the Axim.  It will not be able to restore your system settings and data after the ROM update.  Use ActiveSync and manually back up your files to make sure you don't lose anything.

After the update, my x51v ROM version was A04.  I set about restoring my programs, settings and data.  Everything went back on without a hitch and I was feeling pretty good about the update until the weekend.  Then I started experiencing many of the same issues I had with ROM A01.  Namely, I'm still seeing the processor racing issue and problems powering up.  Other users have continued to report issues with their CF cards disappearing.  And the A04 ROM does not improve the Bluetooth implementation, so you'll not be able to connect to any new devices.

The update isn't a total loss, though.  The wifi signal strength meter works better.  The SD card is no longer lost by the operating system.  And some users are reporting an over-all snappier device.  Although this may just be from resetting the device which brings it to a fresh, initial state.

Microsoft ActiveSync 4.1

Since the initial release of the Axim x51v, Microsoft has also released an improved version of ActiveSync.  Most Axim users have been able to get more stable connections using ActiveSync 4.1.  However, wifi sync functionality is missing and because it's been deemed a security risk, will likely not return.  Microsoft cautions users of devices that are running older versions of Windows Mobile not to upgrade.  That's sound advice.  I still feel that ActiveSync 3.8 was more stable and included more features.  However, version 4.1 does improve some of the conflicts many users were having with firewalls and VPNs.

Conclusion

So Dell brings us a new handheld with many new abilities and flaws.  Those who were hoping for a single update that solves all the current issues have been disappointed.  But the new ROM is definitely a step in the right direction.  I have been using an x51v for nearly a month now and I feel it's got great potential.  I really enjoy the VGA resolution, speedy processor and persistent storage of my data.  I'm also getting really tired of my device periodically not turning on when I press the power button.  I love the form factor and the solid feel of the hardware, but I feel like the software could still use some work.

My verdict is this.  If you're looking for a rock solid workhorse for an everyday PDA, steer clear of the x51v until Dell gets a few more of its "personality issues" worked out.  There's still too much that's new and apparently untested.  However, if you like to experiment with new technology and can get over some reliability and compatibility troubles, give it a shot.  I have no doubt that Dell will continue to release improved firmware.  So things will get better with time.  But depending on how long that process takes, many users may end up feeling pretty let down.

Pros: Persistent storage, VGA resolution screen, Intel 2700g graphics processor, 624 mHz central processor, lower price than competing Windows Mobile handhelds

Cons: Poor Bluetooth implementation, miscellaneous operating system and software issues.
