Is the xperia ion good enough for the time to come?

I'm planning on buying an xpeira ion. It has everything that I need. I especially want this model because this is the only phone within my budget that gives a 12 megapixel camera(and I'm very particular about this. I won't settle for anything less than 12).However, I'm very concerned about the processor. A 1.5 ghz dual core sounds decent but I have to consider the fact that it's a relatively old snapdragon s3.So my question: Is this phone, considering how power hungry all new apps are, good enough for the next 3 years? And will all new apps run smoothly? Also, how good is this phone's processing & graphics power when compared to the iphone 5? Thanks a lot in advance!

Yes it is

Sony company, which has mastered high density sound connect it to audio system and you experience mind blowing music but poor call quality. Another thing the price and its really not affordable at the current price which is mentioned. Don't buy sony phone there service are pathetic… Phones are defective…

No, get HTC

  • Sony Xperia Ion vs Apple IPhone 4S? This guy really wants to trade me, but first I want to ensure it will favor me. From reveiws it seems to be in my favor since both phones are in perfect shape. However, what are your opinions? And will my sim card go into the ion?
  • Polymer Lithium Ion battery toxic? The battery of my iphone 5s was accidentally cut open while being repaired, is there any negative health effects to breathing in whatever the horrible smell coming from that battery was, I have a weird taste in my mouth and breathing feels weird. I wasn't exposed to it for very long. Should I be worried? UPDATE - I'm no longer feeling weird really but still anything I should worry about?
  • Lithium ion batteries? Will a lithium ion battery explode if it is dead, i'm looking to replace my basically non-existant battery life iphone battery and i'm concerned with the risks of possible damaging it during removal.
  • Is the Sony Xperia Z any good? I wanna buy a new phone and i have been looking into the sony xperia z. It looks really good but is it high quality? Is it worth it? Is there any other phone you would recommend to me.don't say iphone because they are all the same. I would appreciate an answer from some who owns a Sony Xperia Z.
