whatever, the idea of lugging around a 15" monitor with me just doesn't appeal...sorry....seems like a pain in the ass
making up problems? There's no way a external 15" monitor compares to an attached 9" monitor in terms pof ease of use and portability...
with the monitor you need a plug in, close to a desk, so you can set everything up, not to mention set up time requires you to run wires, unpack a monitor, find a place for the monitor, it's just a pain. Not nearly as easy as folding open the LCD, plugging in 1 wire and playing.
Of course you could play it in yor car, buy a 200w adapter for $30.
The idea of lugging around a 15" monitor just to play for x360 seems kinda dumb to me, if it's easy to do then I'm all for it, if it means I gotta lug around 2 carrying cases and do a bunch of set-up, find a desk, etc, then forget about it, I'll leave it at home.
I like the idea of one self contained unit, packing an extra monitor around has ALWAYS been an option, but it doesn't appeal to me at all. On teh other hand, something like an atatched LDC taht you simply pop open, now THAT is easy, light, and painless, excellent for a rainy day on vacation.
