I have always had Samsungs and still have my Samsung Monte on Pay as You Go, but 2 years ago i got a Blackberry Playbook as this was ideal at the time rather than carry around a laptop, so i got myself a Blackberry curve 9320, so i could link them both and use BB services to connect to the internet on my Playbook. Nov. last year the 9320 keep disconnecting calls, so took it in for repair and found it was a sim card issue. i was paying at least £20 each month + £5 a month for BB services, so while i was in the phone shop i noticed they had the new BB Z10 at only £11 a month with 500 mins, unlimited txt, 250GB data, well great deal so i took one of these. so to me Blackberry is ideal for my business
