Yip I've used it
Seems alright, easy on the eye and great if you have a magic moment fart over marketplace.
Not sure if they vet there apps as well as google does, you know prescanning for expliots and other nasty's before there made available to the public, you know that kind of obvious thing to do. You can never tell.
If I buy a sandwich from a vendor and it has a virus and I get sick i can easily get compensation compared to buying a application from a broker. Does beg that some level of auditing and vetting for there commision would only make sence and with that done right I'm sure they could get idemnity insurace to deal with any mishaps. But thats like trying to combine health with finance, oh well.
But I must say i do like this on my android tablet and would go as far as saying that I prefer it - though please note I'm still yet to venture into the paid application arena.
Very easy to pick your device unlike some fun on android marketplace.
I must say I'm supprised it's now official as seemed a robust and mature site on many levels. though the tendancy to drag out beta's on generaly freeish stuff is known - how that translates retrospectivly to people who carried out transactions I darn't think about. Sorry Mr Smith about taking you £3m overdrawn there site is still in beta after all would if nothing else get free advertising - though unlikely the aspect of doing financial transactions on sites that are technicaly beta if but in name only does open alot of questions.
Still have to say I like it - even on my $100 tablet it works very well. Also the easily ability to pick your device/phone/torture allows you to download and transfer to your device later on your computer if you so wish.
