I'm sure the readers of this product may want more info, so I'll do my best to provide additional details (G155 comparison included):
The case is made out of thick plastic just like G155, so its sturdy. The dimension almost identical at 20" x 14" x 6.5" excluding handle, which satisfies virtually all major airlines carry-on size requirement. The handle adds 2" and makes the height 16", but no one at airport will realistically factor that in. The screen side of the case is less round, perhaps to accommodate the larger screen. I think this design also strengthens the latch gripping better under stress. The shoulder strap with padding (has UNSC logo) is a greatly appreciated item when an extra hand is needed. The design permits the strap to be attached or removed within a few seconds.
With the case having the same length and width of the 15.6" G155, it is remarkable that GAEMS fitted a 19" screen. Actually, the screen measures 18.5" diagonally but looks bigger than that! The lighting on buttons are all blue (G155 is red). The blue background lighting on two sides of the screen is a nice touch - not fancy so doesn't compete with the game content. Like G155, my PS3 recognizes it as 1080p with 2 audio channels. The display is much brighter and seems faster in response time.
The best part of the display other than size? It's the vastly improved display angle. Horizontally, I can line up 4 kids in front row and all can see the screen well! Vertically, kids standing up in second row can see also! As for the player, I tried sitting on the floor, sitting on a soft mattress (sunk in deep), and sitting on a chair with Vanguard on higher desk. The display angle passed in all scenarios! This wasn't the case with G155. There is a little kickstand allow the screen side to adjust up by a few degrees, which is really thoughtful feature. Kudos to GAEMS for listening to users on these improvement!
Audio and Controls
The speakers are located on the bottom left and right corners. The drivers are about size of a golf ball (1.25" I think). They are open and masked slightly by 5 horizontal bars - more like the cosmetic mud guards installed on 4x4 SUVs! The sound quality is vastly improved. The Halo 4 main menu music is a STUNNING demo of its range and depth. It's pretty good at high and mid-range. The debris and electrical buzzing effects from Halo 4 are sharp and realistic. Bass can be adjusted in menu, and it's adequate. Voice is still deep and clear! It has pretty good power too. I put Vanguard on 70% volume in a room, then go to kitchen about 50 feet away with 3 walls in between and I can hear the music pretty well. I also didn't hear distortion at 85% volume! With such loudness, there is really no need for external speakers to truly enjoy gaming away from home!
The bottom center of the display panel has the same two headset output, an HDMI input with the 7" cable, and DC 12V input from the power supply.
The console rests on a pad. One side has inset shaped to fit XBox and PS3. The other side has a small 9" x 7" footprint, which fits neither consoles (Nintendo Wii?) The two straps are thinner than G155, perhaps to allow better ventilation on the XBox 360 Slim.
The 2 side storage bags can be freely picked up (no Velcro underneath). They are same size as G155. With XBox having an external power brick, one storage bag will be used up for the two power supplies (one for display). This leaves the other for two controllers. Quick thought: since both XBox and the screen display use DC 12V as input, I wonder there is an DC Y-adapter that can allow both device to share one large power supply...
Since PS3's transformer is built-in the machine, there will be extra room available in the storage bags.
Note on Portable powerpacks
I have two battery-based jump-starters with inverter kept in family cars. I used them to power G155, and will power the Vanguard as well when AC outlets are not available (e.g., picnic/camping). Vanguard consumes average of 90 watts (XBox 360S 4GB w extra 256GB HDD and Wi-Fi active) with medium volume and brightness during play. Here are actual run times with the two that I own:Duracell DRPP600 Powerpack 600 Jump Starter and Emergency Power Source
: 1hr 55minWagan Power Dome EX 400-Watt Jump Starter with Built-In Air Compressor
: 1hr 3min
I'm sure with Wi-Fi turned off one can run longer times. Same if the HDD is not needed or replaced with SSD.
When GAEMS released G155, I was excited - finally a practical solution for console gaming away from home. I used it on travel and always in awe just having that ability to play console games somewhere else! Even as a happy user, there is always room for improvements. GAEMS was listening to the passionate G155 owners and all key improvements are in this Vanguard product. After playing with Vanguard for few hours, I'm thoroughly impressed, satisfied, and with absolutely ZERO complaints (for now)! For us console gaming lovers, GAEMS has done a great service to not only make gaming away from home possible with G155, but now with truly immersive experience with Vanguard. It's absolutely worth the price.
