David 4.0
Before this phone I had the Xperia Ray which I loved, but I wanted to try this one so I bought it and I'm really happy with it. The design is great and it's really fast and responsive (It has a dual core processor). I'm a heavy user and so far the only thing that I wish it would be better on this phone is the quality on the videos. It's not bad but they look really pixelated I don't know why but I have a dedicated point and shoot camera which takes great videos and photos so It's not a big deal ... for me. If you use a lot of space for music and movies you should buy another phone with an SD card slot because this has only 8 gigs (Xperia Ray is in the same price range and has SD card). 4 gigs for the phone and apps and 4gigs for your music, photos, etc. I don't use a lot of space that's why I decided to buy it and so far it's great! Really fast and responsive and once it gets Ice Cream Sandwich it will be better. If you're looking for a budget phone this is THE BEST you will find. BUY IF: -You want to try a great android phone. -You want the best unlocked smartphone for under 300. -You don't need more than 4 gig of space for music and photos. -You want a fast and reliable phone -You want a great phone with front facing and rear camera. DO NOT BUY IF: -You want more than 4 gig of space for music and photos. -You care a lot about high quality videos. PROS: -Great design -Good size -Screen is crisp and bright -Dual core processor -really fast and responsive -Sony keyboard is one of the best I've used. It has swype function. -2 cameras: Front and back -LED flash -GPS -Battery life is great. CONS: -only 8 gigs of space -Low quality videos -Speaker doesn't work with google hangouts I don't know why. EDIT Jul.3.12 : 1. I think I was a little harsh as far as video quality goes. It's not that "low quality". It's standard but some pixelation and artefacts make it look bad. Search in youtube for "xperia u video sample" and you'll see it in action. 2. I have had a problem with Google+ Hangouts where the loud speaker is really, really low. The loudspeaker works great for everything other than Google+ Hangouts so if you want this phone for hangouts I don't recommend it unless the 2 I got where defective. I guess you could buy it and if it doesn't work you can return it. More >

ok, so its been 5 months, im the kind that researches hours and or days/weeks for the best features and lowest cost on an item, I was on a low budget and wanted my first smart phone, using a touch screen for me took some practice, I have have big man hands and fingers, but the predictive text helps and now have no problems if I misspell the right word comes up anyway. , like that i can plug into computer for media and updating, no need to use your cell service downloading, just plug to computer ... and internet, much faster updating right after I bought and upgraded to ice cream sandwich 4.0.4! no memory card slot, but had plenty space, i have loaded 150 songs and 130 music videos! still had a gig and a half left. so the stupid obsession with huge amounts of space is not needed unless you keep movies or long clips of media on phone. one thing I disabled Bluetooth and WiFi immediately, and lowered brightness which is still perfect even in outdoors! , and battery life increased. I love that power button is on side, I wish screen was a little bigger like the xperia p and speaker is in back, best position for speaker is on side like the xperia p. If I could afford the upgrade to xperia p, I would get it, but Im broke.Speed is great, I have experienced no video lag whatsoever, everything has been smooth. I must say out of everything, I was shocked when watching the music videos, the resolution and clarity/brightness was amazing!, Im still in awe when watching, my friend has a phone that costs almost 3 times as much and looks no where near as good in video quality, it really freaked me out, its the best picture Ive ever seen seen! this is not a cheap feeling phone!, it has a good weight and good thickness and feel. This is the perfect featured phone for me, best price, a phone like this should cost more, but I'm glad it doesn't, it came with screen protector and charger adapter to plug in wall or plug to computer usb.
