I'm also confuse with the two... I went looking for some video reviews on which has a better performance..
I'll buy one of those soon, but it seems Touch Pro is still very expensive @ Digital Walker in SM CEBU, @ whooping 50,800 pesos. Same price with some of the seller in Manila I've seen online.
Sony Ericsson shops offer Xperia @ 44,000+ (I don't know exactly the price and hoping they have monthly installments coz I forgot to ask).
I think I'll go with Xperia as it has larger screen than Touch Pro and Xperia is available locally here sa Cebu. Touch Pro is one hard-to-find product here sa Philippines but for sure, after few months or maybe a year, it will be flooding with 2nd hand touch pro.
btw, IMO, Xperia wins with the performance.
