5 out of 5 eggsPerfect

Pros: Amazingly compact phone -- better than other some new SE's on the market. These are particular stand-outs:
o Highest DPI of any SE phone
o Largest battery of most SE phones in its class -- 1500mAh
o Smaller than any other SE phone currently on the market, as of July 2012
o Keypad smallness can be obviated by installing Swype, which works amazingly well.
o FM radio!

Cons: o Only single-core
o No mechanical buttons for back & menu buttons, making it easy to touch them during touch screen operations
o Needs bootunloader to be unlocked to install CyanogenMod, even though phone comes "unlocked". (If you don't know what this means, then it doesn't apply to you:) )

Other Thoughts: Oh how I will miss Sony making this phone. So sad that the marketplace is asking for larger fatter phones.

4 out of 5 eggsThe little phone that could

Pros: The Xperia ray is one of the few or maybe even the only one of the small and good Android phones. It is pletty fast, has a decent batter life, includes the full range of modern smart phone hardware including but not limited to the image stabilizer for the camera AND you can get it with the US warranty for under $300. Additionally, Sony promised an upgrade to Ice Cream Sandwich in Q2 or Q3 this year, will wait and see.

Cons: Wi-Fi connection gets stale (quite often) with some routers and/or some wireless router settings. It happens with my Netgear WNR3000 but not when I use open Wi-Fi say in Starbucks. Restarting Wi-Fi on the phone (temporarily) fixes the problem.

Other Thoughts: Some people complained about the phonepad keyboard layout but that can be easily changed to a (full) regular Android keyboard in International keyboard settings / Portrait keyboard : Full keyboard

5 out of 5 eggsSmall like Little Mac, Punches like Iron Mike

Pros: It is very pocketable, which was what I was looking for. You know how hard it is to find a small and fast Android phone? Very! I had an HTC Aria and I love that thing, but it is pokey even with CyanogenMod loaded. The memory was miniscule. I had to be really want an app to have it installed. No fun and games at all on it. So I nearly had a heart-attack when I found out Sony made this little beast. And it is a beast! Enough memory to install all the apps I want without having to choose which one to cull. The processory is a 1GHz Snapdragon (single core) which is a fine processor. Do you know what I came from? 600 Mhz on the Aria! The battery life is usable. From what I can gather so far, it'll last about 8-10 hours of moderate use. Standby will last almost 2 days.

Cons: There is not alot of heft to the phone even with the 1500mAh battery. It's back shell is thin plastic. Not metal. That isn't a complaint since it won't interfere with reception. The complain is how delicate it can feel. I might be overstating it since I've only had it for a week. I just bought a gel skin for it and it feels much better now. Not like I'm holding a hollow egg any more.

5 out of 5 eggsWhy do phones keep getting larger? This one is small and ROCKS!!

Pros: I am totally impressed by this phone. Screen is awesome, colors, brightness, dimness, quality etc... Responsiveness is great. I dont know what other reviewers were talking about with too responsive or not responsive enough, it works great, even with animated menus on. If your not used to capacitive touch, maybe that is their problem?

Camera is great, with flash!

Processor is crazy fast. 1 ghz scorpion or snapdragon, sites quote different names, either way FAST!

Battery life is decent. All day, 2 or 3 short calls, inet browsing, 10ish texts, and bluetooth to car stereo with web stream on the drive in and home (15min ea) = 20% or so by 6pm. Not bad i think.

Speakers are awesome, reminds me of my nokia N-series days. If you had one, you know what i mean.

WIFI tether works out of the box.

Can install non-market apps no problem.

Back cover is the color of the phone, so dont like it, just buy another, BAM, phone is a diff color. (ahh yes, the nokia days!)

The best....

Cons: built in touch keyboard. Seriously? a numberpad? LOL go to the market and download a new one. easy fix.

Google and sony apps everywhere, cant uninstall them. Have to root for that. Phone is by no means slow or crippled with them though.

Lastly, If you have fingers that are as fat as hotdogs then this phone is NOT for you!

Other Thoughts: Buy it if your tired of phones as big as VCR tapes........

4 out of 5 eggs3G works with AT&T only

Pros: I DON'T OWN THIS PHONE YET, but I do own the X10 Mini, which I love, but hate the fact that 3G does not work with T-Mobile. I can get Edge, but that is not so fast. I don't want to switch to AT&T. Just keep that in mind.

Cons: No 3G with T-Mobile.
