Under the bonnet, the M900 is identical to the F900, so you get the same quad-band GSM, Edge, 7.2 Mbps HSDPA and 2Mbps HSUPA 3G, 802.11 b/g Wi-Fi, A2DP Bluetooth and a Samsung S3C 6410 533MHz processor with 128Mb of RAM to play with. The operating system is Windows venerable Mobile 6.1 Pro with Acer's bespoke Shell GUI draped over it with various degrees of elegance.
If fingerprint reading fails, using a password is still an option
Acer's Shell interface does the business, but hogs resources
At last, landscape browsing with Opera
We still think Acer Shell is too slow and too resource hungry, but on the M900 it performs no worse than it does on the F900. Thankfully, one of the shared glitches of the two handsets – a rather wayward accelerometer – is cured on the M900 with the screen swapping to landscape when it’s slid open. This allowed us to view the Opera web browser in landscape, something we didn't managed to accomplish with the F900.
The GPS rig is another area where a small but significant enhancement has been made over the F900. On the M900, it's now assisted GPS. This resulted in a noticeable improvement in the time it took for the phone to find itself when the GPS was switched on.
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.
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.)
