For the second time since I bought it 11 months ago, my O2 hung so badly that it couldn't be rebooted the usual way (by poking a hole at the base of the device). This time the warning message I got, shortly before it hung, was along the lines of 'Out of memory'.
After numerous attempts in vain, I had to do a hard reboot, resulting in my phone data being lost. Fortunately I was at home and managed to install the latest Windows Mobile patch (in the hope that it's more stable), and re-install my Bible software. Fortunately, all the data in my memory card was fine.
The first time it happened to me, though, it was more scary. I was on the road, heading towards a colleague's home for dinner. The O2 mini was lying peacefully in my car's cup-holder. I can't remember exactly when it happened, but I noticed the screen didn't look right anymore. I touched it with my fingers and it didn't respond. Rebooting didn't help.
Naturally I didn't have the O2 manual with me, and I really needed to get it working again. I did a hard reboot and then realised that all my contact data was wiped out. How was I to find my colleague's place now? I couldn't even call for help. Fortunately, I remembered the road she stayed on, and found the right condo. (Note: Prayer does help!!)
But it was a harrowing experience. No phone I've used before, has hung so badly on me. At worst, my Nokia phones would just get slower and slower. But even when they hung, I could restart them without problems. I noticed however that Windows Mobile doesn't totally close apps after you've exited them. So after a while a lot of RAM is being used, but when you check, no programs are running in the background. The only option left (as far as I know) is to reboot the Mini.
That's the most serious flaw in my Mini so far. The user interface sucks for SMS too - why is the numpad so small and pushed to the side? And if you meet an old friend on the street and he rattles off his mobile number to you, you can't just key in his number, then 'Save as new contact'. You must go into the address book, create new contact, then scroll down to the mobile phone field, and enter the number.
Having said all that, it's cool to view my PDFs, Powerpoint slideshows (yes, all one of them) and keep Excel spreadsheets on my little Mini. But these are all just NICE to have. I'd very much like a phone lets me SMS quickly without fumbling with my fingers / using a stylus. A phone that lets me call people from my address book with minimal scrolling and searching, and won't hang on me again.
