Around the House
Around the house, this device works really well because I can load up my anime and just watch it in any part of my house including the closet. It's not as uncomfortable to use in bed as my Toshiba M205 Tablet PC while laying down because it it's about 1/4 of the weight. It also makes a great couch buddy while I'm watching TV and then chatting online, even though my PDA is smaller and can already do that... The U750 also works great in the kitchen because it's small enough to sit anywhere and you can use it to read off recipes. Rotating the screen is also useful for reading and jotting down some quick notes.
I wouldn't use this as my main computer to do my more serious work at home and it certainly is not meant to be a desktop replacement, even though I am using it to write the review at this very moment. Just for kicks, I hooked this up to my Bose surround sound system to use as a media center to stream in music off the network and it works great. Again, the big advantage the U750 has is that it can fit anywhere and I can't stress that enough.
On the Road
Using the device on the road is where the U750 suffers. This is very ironic because it is such a small device. It was meant to be portable but design flaws keep it from being so. The U750 has only a 2.5hr battery so it won't really last on those long plane rides unless you ride first class and have an outlet available to you. If you are out on the field and work 8hrs a day like I do, then it will be rendered useless very quickly and you have to find a place to charge it and have it always plugged in. This will then force you to have ONE MORE thing to carry including the dock if you want to use the keyboard somewhere.
Using the U750 outdoors was no problem thanks to the transreflective Xbrite screen because it didn't have any real glaring problems like other portable devices. When using it to write quick notes or as an organizer, it sometimes became a bit frustrating to use because it was too big to be used as a PDA. There are a lot of situations where I just got tired of carrying this thing around no matter how cool the concept was and just left it in the car and took my PDA and phone with me. Costing $2000, a device like this shouldn't be tossed aside but unfortunately it is. It's also cool that it comes with a displayed remote but I wouldn't take this thing out jogging or use it to replace my MP3 player because it's just to big to be one.
Games
A lot of people would be curious if the U750 was capable in playing any games. Surprisingly, it performs quite well in this department and it will blow the PSP and Nintendo DS away if one were to use this as a portable gaming device. Warcraft 3 ran beautifully on this without any slow downs or graphical problems. The U750 works best for RTS games because of the use of the stylus.
CounterStrike ran really well too and the experience is actually a lot better especially for sniper fans. Just find your target, tap the screen and their dead. Also the built in WiFi is great because you can play online anywhere in the house or wherever there's a wireless signal. World of Warcraft ran fairly decent, but there were occassional moments where it stuttered in the game.
Excellent portable entertainment device, but not laptop or PDA
The Sony Vaio U750 is a lot of fun to carry around and play with if you want to take some anime/movies or games on the road but because of some design flaws and battery life, it suffers as a laptop. This is actually a great idea by Sony but it wasn't well thought out enough for the average consumer. Sure it has a great screen and it's light but you're going to end up having to carry too many things for this to be truly portable. To me, the U750 is more of an expensive novelty item rather than being a serious business device. Hopefully, Sony will continue on with the U series concept and fix the flaws with the device.
