Laptop and travel bag makers Tom Bihn and Mivizu are among several retailers who have announced new iPad products today, and both have new, more streamlined cases for the iPad 2 that are ready for pre-order. Mivizu offers sleeve-style cases to fit the modified, thinner form factor, while Tom Bihn is offering their Breve travel case that works with either the original iPad or the new model, and offers room a phone and charger -- but not much else.
