[Sony Xperia T, TL, TX, V] vonotny:
I've been using the Xperia Ray for almost a year now, and before that I had a Mini Pro. I upgraded to the Ray because the Mini Pro's screen was too small and too low-res, and now I'm looking to upgrade from the Ray because I find I need more internal storage and more power. I don't play games or anything, but I frequently use apps like Instagram, Flickr, Flipboard, Dolphin Browser etc., and often my Ray breaks down when there's more data incoming that it can handle. Also, the internal memory is a joke. I do however love the high-ppi screen and the form factor.

Originally I didn't want to go larger than 4" with my next handset, but it seems you'll only get a decent screen when going 4.3" or bigger. Also, I'd like to stay with Sony as I just love their design and am so used to their UI (despite using Go Launcher on top of it.)

So, I narrowed it down to the late 2012 models T, TX and V. The Z is definitely too large for me, and the other current Xperia models don't do it specs-wise. Each of the three has something going for it, and for the life of me I can't decide which one to get. So if you can help me by pushing me in one or another direction, I'd greatly appreciate it

So here's my list of pros and cons for each handset. They all have 720 HD displays, which is great. I don't want to go with less resolution (qHD doesn't do it, it's not a significant step up from the Ray's 854x480 display.) They all feature the gorgeous Arc design which I love. However, there are some differences.

Xperia T

Pros:

- Moderate price, especially when bought used. (I live in Germany, btw.) Can be had from ~ € 250.

- By far the largest battery of the bunch, @ 1850 mAh. (I am used to charging once a day, though, and typically my phone will last well beyond the end of the day.)

Cons:

- No exchangeable battery.

- Side flap that covers microSIM and microSD slots could eventually break and get lost.

- 4.55" is a bit large for my taste. I held it and found it tough to operate with one hand.

- Screen reportedly not very good (as compared to other models).

- Awkward button layout.

Xperia TX

Pros:

- Slightly silmmer profile than the T, which makes it look a lot nicer.

- Better button layout.

- Reportedly the best screen of the bunch.

- Placement of the screen makes it look more balanced (T has it more to the top).

- Xperia logo lights up (okay, this is a gimmick, but I love it )

- Exchangeable battery.

- Back cover offers better protection for microSIM and microSD.

Cons:

- Only 1750 mAh battery, but the difference to the T isn't that big.

- Higher price as it cannot be bought used over here. ~ € 350 upwards.

- Slightly wider and larger than the T, plus the 4.55" screen which I find just a tad too large.

Xperia V

Pros:

- Smaller than both the T and TX due to the 4.3" screen, so this could be closer to my preferred size.

- IP55/57 water and dust proof. This phone could last years.

- Offers LTE, should I ever upgrade my carrier or my contract.

Cons:

- Don't like the design of the front as much as that of the TX, especially the lack of Xperia logo at the bottom.

- Pretty steep price at least at the moment. Lowest online price somewhere around € 400. May drop once used units get on the market.

- Only 8 GB of internal memory, although that would probably suffice as I'll be using it with a 32 GB SD card anyway.

So there ya have it. All three have their pros and cons. Currently, my favourite is the TX, but that's mainly because I think it looks the best, and because it is said to have the best screen. The V however is a serious option due to its water- and dustproofing and the fact that it offers LTE. Doesn't look as nice as the TX though. The T ranks last on my list, mainly because the battery cannot be replaced, and because I think it looks bulky and unbalanced. The price however is ideal.

You see my dilemma? If I had money in spades, I'd probably get both the TX and V, try each for a while and then decide which one to keep. But as it is, I have to really justify shelling out that much money (even € 250 I consider a lot to spend for a phone.) While I am absolutely in love with the TX's looks, I'm debating whether the T may not be the more rational choice, or if I shouldn't get the V which has LTE and is water- and dust-proof when I'm spending that much money.

What would you do in my place? Which one should I get? Also, those of you who own any of the three, what are your experiences? Do you love yours, or would you rather have one of the other two models?

Thanks a bunch in advance for your help!

P.S.: Root-ability is also important. Are there any differences between the three devices in that regard?
