EDIT: and patsu probably has his Vita by now, he should be getting it today. Better post some impressions!
Yeah, I was (still am) tied up. Have a lot of things to say about Vita. Guess I'll have to post random thoughts.
Yes. It works better than the PSP one, but we still have to use the dpad to navigate XMB. Feels like a huge step backwards from touch screen UI. ^_^
As for the hardware itself, I'm quite pleased. Has a solid, quality feel to it. A step above even the original PSP, which I always thought had a quality feel to it, especially compared to the later models. The GUI isn't as off putting as I thought it would be, but it completely lacks the elegance of the XMB, and the clean, simple look of ICS and iOS. I think some will find it's design to be excellent, but it's just not my cup of tea. The screen is excellent, as has been reported. I don't like the way Friends List and messaging are separate apps that you have to launch. They should be a better integrated part of the experience, IMO. But I don't know what happens if a friends contacts you if the app is not running. If it launches automatically, then its a moot point.
The UI attempts to insert a community angle (LiveArea screen) into every app. Every app has its own LiveArea. As a result, launching an app always takes 2 steps. First tap in the Home screen opens the LiveArea. Second tap in LiveArea starts the app/game. Would be great if they allow us to double-tap in the Home screen to launch the app/game right away. Other than that, it's almost like the original iPhone OS. Very snappy and smooth.
The web browser has the following issues:
* Scrolling (upwards or sideways) sometimes leave the screen partially updated for 2-3 seconds. This is a bug.
* Browser doesn't rotate when you rotate Vita (i.e., can't view in portrait mode)
* No way to jump to the browser address field right away (by tapping on the info bar). Have to scroll all the way up.
* Since Vita OS does not have text services like a general purpose OS, copy-and-paste is missing. The text edit field also doesn't allow you to drag select (for copying or bulk delete).
However I prefer to use Vita for web surfing because of the larger screen and the dual hand hold. It's more convenient and less tiring when I browse in bed. ^_^
Typing is also faster because of the larger virtual keyboard, and more sophisticated text completion. The side menu is also very convenient for performing common actions (e.g., open a bookmark, display all pages). Since the side menu is always there, these actions generally takes 2 quick taps to execute.
Friends List, Group Messaging and Near need to be reorg'ed a little. Yes, Friends and Group Messaging should be together. Some functionalities in Near may be more appropriate for Group Messaging + Friends.
In addition, since Vita can multitask well, these apps should call on each other to perform their specialized functions (e.g., Near should launch and update Friends' activities log, instead of embedding the Friends' log inside itself).
Despite these details, the overall Vita environment is rather pleasant to use. The OS may crash once in a while. Hopefully the new 1.61 update fixes them.
EDIT:
My biggest gripes so far are:
* Sony should expand Friends List limit to 200 or more. I have already hit the 100 limit months ago. I can't add any more Vita friends. ^_^ How 'bout start with PS+ members first ?
* Should speed up backup speed. Either add incremental backup option, or implement a Sync function like iOS. We should not need to perform full backup every time.
* Still waiting for that multitasking fix (for switching between web browser and game seamlessly).
EDIT 2:
Near is quite similar to what I wanted in Home (e.g., summarize and highlight community activities in real time). Unfortunately, it is not available to PS3. And Home is not on Vita. Otherwise, it would be interesting to enhance Home with a 2D UI, and Near's "dynamic" community analytics.
