AJ MacLeod said "My 9105 has a battery life that rivals the Nokia brick that it replaced - even now, three years on, it'll stretch to about a week of normal usage (i.e. mainly calls and the odd email/BBM) or a few days of heavier usage (lots of photography / GPS / browsing )"
Sure you can get almost a weeks usage from a tiny 360 x 400 pixels, 2.25 inch screen, with 3G. The modern features of todays phones EAT batteries. 4G, modern internet functions, etc. Try using this site and others on that 360x400 screen.. it blows. When I use my 1yr old Android phone, I view sites in desktop mode in 1280x720 res. GPS on todays phones are more accurate than 3+ year old tech. (* According to a phone site GSMArena, Talktime on the BB 9105 = 5hrs while the Galaxy IV is 17hrs)
What BB/RIM is doing is NOT good. Their OS should be portable for a slower phone (hence, there are NEW cheap Android phones today with single core CPUs @ 800~1000mhz using Android 2.3). Its bad to be selling "new" phones that cannot RUN new software. Think of the Days of Amiga when C= was selling the A1200 with ADOS 4.0, A600 with ADOS 2.2 and the A500 with ADOS 1.3.
A person buying the older phone has not future support, software wise. They will most likely buy an Android that WILL run the software they want or need.
I'm not a Blackberry hater. Their older phones did suck many ways, thou. Their new phones are top of the line... but I'm not seeing much advantage over Android. With newer versions of Android 4.x and 5.0, you can run two APPS on the screen at the same time (certain ones, as they code them). So today, I was able to TEXT and use Google Maps at the same time - which was handy.
BB screwed up years ago, taking over 3 years to release an OS upgrade and have orphaned their tablet owners. BlackBerry tablet is *DEAD*. They aren't even going to try to make a new version or upgrade the OS for their only 2year old tablet.
BlackBerry is a mess and Microsoft is not much better - but they have far bigger pockets.
