Beyond the usual WinMo software package, Acer bundles the same RDS FM radio and music player that it does with the F900. You also get a media streamer, business card photo manager, and voice command software. Sadly one thing they don't give you is a 3.5mm headphones socket so you are stuck with the all-in-one miniUSB headset. Again, as with the F900, video playback is handled by Windows Media Player Mobile.

End of the line? Still, the best Tempo yet
When it comes to battery life and call performance it's hard to slide a cigarette paper between the M and the F, so you can still expect crisp, clear calls, a decent speaker-phone and a solid two days of average intensity use from a full charge of the 1530mAh battery.
Like the F900 the M has price in its favour, being available unlocked for around the £450 mark. That's a good £40 cheaper than we generally found HTC's Touch Pro2. The price gap is not as great as that between the F900 and HTC Touch HD but, on the other hand, the M900 is closer to the Pro2 than the F900 is to the Touch HD.
Verdict
Acer's final Windows Mobile 6.1 handset is its most compelling smartphone product to date. Yes, the basic failings are the same as we noted on the F900, and yes, we would recommend swapping Acer's own Shell UI for Spb's. Nevertheless, the combination of a fine slide out Qwerty keyboard, a 5Mp camera and some subtle additions like the 3-way jog wheel and assisted GPS keep those failings from coming so far to the fore. Despite being something of a chunky monkey, it’s also a better-looking device than the F900 in our book. ®

The A key and Tab
Its too easy to hit tab instead of A (or even both!), they should have been seperate keys. I've often got the A key jammed down as a result of trying to over compensate not pressing the Tab or its not registered the A key at all.
The firmware is awefull at the moment. You can't use mail to save attachments to the SD card as its not very "compatible" with some... although you won't be show any error messages. If you setup like this then you may well get blank screen of death which requires a battery out. The new F900 firmware is out already (which is a positive move by Acer) but it still doesn't cure this problem. If your like me and actually use this for real business work, a few docs/pdfs/speadsheets and thats all your main memory eaten up and out of memory errors .... not acceptable.
I'm currently in the process of returning it to Acer under warranty. A phone that keeps locking up, requiring a reboot, is not usable and "not fit for purpose".
Another issue i've just found, try and get normal headphones working with it ;-) A mini-usb->3.5mm adapter just doesn't work (the phone doesn't detect headphones). This is a REAL problem for me as well as the stock headphones are crap and don't work very well under a crash helmet - i can't hear the raido over my engine noise, something I have no issue with my normal headphones. Try locating 3rd party headphones, i can't find any for hours of searching....
btw, the ' via a symbol key? Many of us on the Acer/Eten forums would love to know which key you pressed in conjunction with the SYM key 'coz its not marked on the keyboard.
Rather Nice!
Bought one yesterday. Very pleased with the purchase, though my fence-post fingers don't make for a pleasant experience with the keyboard (but that would apply to ANY mobile phone keyboard).
My first impressions are that I bought a good 'un with respect to the several competitors out there. It does everything I expect it to, and though my experience of mobile phones in general is relatively light (I don't live to use a mobile phone like some people do) I'd be happy to recommend this little beaut to others.
I understand you can make telephone calls with it too.

Thanks, Al. I'll look into Mobile Shell. The jog wheel was so useful on my P910i that I ended up playing the chess game more than anything else, solely because you could play it one-handed while carrying stuff around; where possible I still use the four-way controller on my G900 rather than smearing the touch screen with my greasy mits, so the complete reliance of the TP2 on the touch screen bothered me.
I guess my only remaining hesitation is the lack of control key (mostly for cut and paste, occasionally handy for an editor, although maybe you can remap something else), the reports that reception is a bit dodgy on the m900, and whether the memory limitation is going to impact on my web browsing. (My current firefox is sitting at ~1GB, but I probably wouldn't have so many tabs open on a mobile... I don't know because my G900's battery dies five minutes after doing any 3G browsing.)
@Andrew Garrard
If I had to choose I'd say HTC's TouchFlo 3D is the better of the two UI's, but I think Spb's Mobile Shell v3.0 is better than both, being faster and more adaptable, so I'd use that on either handset. The jog wheel on the M900 works just fine - nudges up and down moved the highlight quickly and a simple push activated whatever was highlighted.
Regarding the keyboard, I didn't come across any problems with the 'A' key and checking the block of copy I typed in as a test I see it has two apostrophes. Two weeks after the handset went back I can't honestly remember where the apostrophe was, but it certainly had one! I seem to recall it was brought up by the 'Sym' key - not being a "problem" I didn't actually make a note of it. The voice command software works well too - no better or worse than any other handset I have tested.
In short if the choice was mine I'd go for the M900 for the larger screen and better camera at the lower price but with Acer Shell as the GUI.
Obvious question...
So how *does* it compare with the Touch Pro 2?
The Touch Pro 2 has more keys (including a control key), possibly a more responsive touch screen (?) and more RAM - oh, and official WinMo 6.5 support. The m900 has a slightly larger screen, A-GPS, official FM radio support, a better (or at least higher resolution) camera and the jog dial I've been missing ever since I switched to a WinMo phone from my P910i. Also some oddball features on each side - speakerphone on the TP2 and the fingerprint reader on the m900 (I have one on my G900 and never use it).
So: How is Acer's GUI compared with TouchFlo 3D? (Does HTC's greater experience in making WinMo phones lead to any extra polish?) Is the jog dial any good? What's the voice control like? I don't care about the 3.8 vs 3.6", and the lack of control key might be a killer, but Monty's comment about the keyboard scares me a bit. That said, frequent BIOS fixes are a luxury I wish Toshiba had achieved.
Still pondering... (I was going to order a TP2 next week, so this is a well-timed review!)
