Theres certainately a healthy range of devices being used! My dad got the new ipad 2 for his birthday but he isn't letting anyone near it, but I may try to use my ancient ipod later on this weekend! I can't say i've tryed any Android devices yet but they all seem to be alright so far. For now I'd rather have Apple products to be frank, other companies just aren't as classy yet (but are also not as overpriced)
