I've been reading all the "N900 is dead" threads, thinking I'd quite like to keep mine alive for a couple or three years, until something truly better comes onto the market.

So, this is a "what's changed since you bought your N900" thread, I'd like to know what you have done, or are doing, in the name of keeping your N900 for longer than you otherwise might - whether new hardware add-ons or improvements to software.

In my case, the list looks like this:

1) Reflashed a month ago to de-crap the phone and reinstall only what I know I need. Works much better for it.

2) More vicious overclocking than I'd have dared a year ago, we're stable at 1000MHz - on the basis that I can replace the whole phone via eBay these days and Nokia's warranty is all but irrelevant now. Seems to work fine.

3) Finally replaced Microb with Opera and used the browser-switchboard to make default. Works better than last time I tried, rather pleased with it now.

4) Added mBarcode - I didn't even know we could handle QR codes - then found a menu to launch Flashlight, Camera or mBarcode on opening the lens cover. Why didn't I know about this before?

...and now onto the hardware, which is where I'd really welcome any thoughts on what's new...

5) the battery life still bothers me on occasion, and whilst I've read dr_frost's works with interest, I'm not sure even a Scud will cut the mustard. The advent of iPads means that USB external batteries have come on in leaps and bounds and I've just ordered up a 7000mAh pack that should itself be compatible with charging from the N900 charger. Had similar before, but they've improved...will post back when it arrives.

6) the speakerphone functionality is sincerely shite, callers complain whenever I use it. Wondering about adding a dedicated BT speakerphone glued to my monitor... anyone do something like this?

7) 32GB Class 10s from a variety of manufacturers are actually in real physical stock at retailers. If truth be told I haven't filled 16GB, but I could use far more if I had some half decent headphones.

8) Marketed in parallel with the N8 (ugh), the Nokia BH-905i headphones have just taken a nice fat price cut and they start to look very tempting. Anyone have any practical experience with these on an N900?

I reckon with a few new toys, I can turn the N900 into a much more functional media machine and simultaneously fix the battery and hands-free issues. Couple that with such software optimisations as have been developed over the last couple of years and I probably have something I really WANT to keep alive...

So, those of you planning to still have your N900s through the 2012 Olympics and beyond - what have you discovered recently that's new since you bought the phone?
