Acer Tempo M900
Acer's last and best Windows Smartphone?
The card slot is said to be good for 8GB and that was the largest capacity card we had on hand to test it with. There’s also a three-way jog wheel which is a handy addition to the control portfolio, as the M900's touch screen could do with being just a little more reactive.
The fingerprint reader also functions as a navigation pad
The bottom of the fascia is home to five buttons, two to start and end calls, one to fire up the GPS system and Google Maps. Another takes you back to whichever of the three Acer Shell home pages you were last looking at. Unlike those featured on the F900, the four fascia buttons physically move when you press them, making the M900 a rather more satisfying handset to use.
The curious little central button between the GPS and Home buttons is actually a combined finger print scanner and navigation pad. In the latter function, it proved a bit hit and miss, being rather too small and too far recessed to allow for reliable or accurate use but at least you can disable it via the settings menu.
The finger print scanner worked exactly as advertised and accepted our four set-up swipes at only the second time of trying. We had no problems with reliability either, the scanner always accepting our print swipe on either the first or second attempt. If the scanner does throw a wobbly you can simply type in your four digit PIN number to unlock the handset.
Unlike the HTC Pro2 or the Nokia N97, the M900 is a simple slider with no fancy screen angle articulation. The keyboard itself has 41 individual keys and is laid out in a slight bow from left to right. We found the keys to be nicely sized and weighted, making rapid and fault-free typing a cinch.
Well-spaced keys allow for more accurate typing
We also liked the soft yellow glow that illuminated all the function keys. These include the numeric keys, the M900 keyboard being laid out in four rows as per the HTC TyTN II, rather than having a separate row of buttons for 0-9 up top as found on the Touch Pro and Pro2.
