IHT reviewed Toshiba HD-A1 and concluded that you should not buy one yet for the 3 reasons:
Reason 1: The average person can see the difference in picture quality, but only on a big, high-definition screen, preferably side by side with a standard DVD signal. The leap forward is nowhere as great as it was from VHS to DVD.
Reason 2: For a brand-new technology, the A1 is a reasonably priced razor – but it’s got a serious blade shortage. Only 20 films will be available by the end of this month, and only a couple of hundred are expected by the end of the year.
Reason 3: This is the big one: You could be placing a very big bet on the wrong horse.
