We liked

On the plus side, the 3.0 megapixel camera is a little better than we expected – it doesn't have a lot of fancy extras, but the basic picture quality is pretty decent.

The web browser too works well, backed up by HSDPA 3G or a broadband connection via Wi-Fi, though it's let down a little by that keyboard and the smallish 2.8in touch screen, so finding your way around the internet is likely to be a two-handed affair.

Onboard memory is small but there's plenty of room for more via microSD card and it comes with Microsoft Office, so you can view and create Word, Excel and PowerPoint docs on the move.

But it's the dual-SIM aspect that really sets this phone apart. If you have a double life, whether it's between home and work, or home and abroad, and really only want to carry one handset, it's worth considering for this alone.

We disliked

The bulky, chunky casing looks ugly and feels uncomfortably heavy in the pocket. The Psb Mobile Shell interface goes some way to making it a one-handed device without having to resort to the stylus, but doesn't really go far enough, and we found ourselves resorting to the stylus on key functions when we really shouldn't have had to – making a phone calls for example, or writing with the keyboard, which is too small, we suspect, even for those with much daintier thumbs than our own.

It's also a bit underpowered in the processing department with just 128MB of RAM, which soon started to struggle once we had a few apps running at once. Diligent apps management is essential.

Verdict

We really like the idea of a handset that accepts two SIM cards, it's just a pity that it had to be this unforgivably clunky and unlovable one.

The world of smart phones, even the Windows Mobile variety, has moved on in leaps and bounds in the last couple of years and the Acer DX900 feels like a throwback to an earlier age.
