iPad 2 demand remains "very strong," according to BMO Capital analyst Keith Bachman. He also adds that Apple's supplies have improved, except when it comes to "the most popular models." The leading model is reported to hold 32GB, although whether it's a Wi-Fi or a 3G tablet is unmentioned. Wi-Fi iPads have traditionally been the most popular however, as they're cheaper and 3G is less essential with tablets.
