I was at Glorietta (one of the popular malls in the Philippines) today and found out that the O2 Xda Zinc is already displayed on the store shelves. The price is around Php 49,500 (US$ 1,013.31) which is exactly the same as the Dopod 838 Pro.
Comparing the Xda Zinc and the 838 Pro, it seems that the latter has the better advantage when it comes to features. Quadband GSM, Triband 3G, and HSDPA are some of the advantages of the 838 Pro. The Xda Zinc, however, was made by Asus and being a former Asus Pocket PC owner, I’m sure that the quality of this device is better than the other Xdas made by Quanta.
I hope I can test an Xda Zinc soon and write a review of it.
