"Put it this way can i see my mum installing chevron and side loading a xap file onto her phone?"
Your mum won't do it. But YOU (or any other tech savvy member of her family) would do it for her instead. Don't be so naive into thinking that because it's 'too difficult for joe average' that joe average won't do it. Look at how easy it has become to 'root' iPhones (or Android or Symbian phones) these days. While the market for iPhone is EXACTLY that same joe average that supposedly won't tamper with their devices!
"Most of these issues won’t be solved buying a windows phone"
Exactly the reason NOT to buy a Windows phone 7 phone in the first place (whether it has an LG, Samsung, HTC or Nokia logo on front). Why buy a same phone as anyone else with the same abysmal battery-life, the same ridicule facebook/twitter-integration, the same crippled agenda and same lack of features that current Symbian-users, in the case of Nokia customers, take for granted.
I find it NORMAL for my phone to last 2 days, I take it for granted that I discretely sync my PRIVATE contacts from my PC with the supplied USB-cable (been doing this for 10 years why should I change my habits?).
I take it for granted that my phone records phonecalls while I'm driving (actually standing in traffic jam but still prohibited from using a cellphone). I've been doing it since I got my SE K750i, Omnia SGH-900 and Acer Neotouch especially since traffic problems become much worse over the last years. Finally I have a phone that can do this AUTOMATICALLY without me pressing any button at all... even when I'm using (as the law dictates) a head/handsfree-set in my car.
I find it normal that the adresses from my contacts and AGENDA can be utilized by the inbuild proper turn-by-turn navigation software. Withouth importing them from one into the other.
I only buy tools when they conform to my needs. And as long as the new-kids-on-the-block DON'T adhere to MY needs they won't come in! It doesn't matter whether it has a Samsung, Apple or a Nokia logo on the front. It doesn't matter whether they run iOS, Android, WP7, Bada or Symbian for that matter. Fullfill to MY needs and I'll be your customer otherwise I won't! Period! I this case the prime reason to choose a Nokia WP7 phone just got debunked!
Nokia's naivity into thinking they gotten the chicken with the golden eggs (microsoft), while everybody else thinks this chicken is a turkey, got them into a bigger mess than they're already in. Congrats Nokia... job well done. The phones barely left the factory floor and they're already completely ridiculed!
