thanks zia..fortunately i am using an innov8 as well ..so i can give you a good comparison.
if you are a windows mobile lover...xperia no doubt i personally think is the best set for it nowadays.You wont regret buying it.
but if you are not into windows..then innov8 is the king of mobiles..its got everything a mobile should have..symbian,excellent camera,ample memory space.i personally think right now no non-window mobile comes close to innov8.
hope this helps.
