Blackberry Maker RIM launched a holding site ahead of the launch of its Blackberry App World (the equivalent to Apple's AppStore), and it had a little surprise in hand: billing appears to be handled via PayPal (the fine print does not need translation: "to be able to purchase applications from BlackBerry App World, a PayPal Account is required").
This is two things: a) a massive win for PayPal and b) and nice move from Blackberry because PayPal is one of the simpler mechanisms, which will feel, like, so totally easy to many users (everyone who has tried to download applications and pay via credit card on their Blackberry will know how onerous it is/was).
I am thrilled to see this coming on. Apple has had 9 months free reign, and it's about time that its competitors step up and bring commercial stores out. Blackberry will be fantastically suited as - due to e-mail having been its central USP - its users traditionally are on data plans anyway, and will therefore be less reluctant to dig in properly.
