Hey everyone!  So I'm thinking about getting a 360 for when I head out to grad school (ditching cable and going with Netflix and Hulu Plus, so figured I'd get a 360).  I have laptop (Macbook pro 13" 2011 model) and was thinking about saving money and just getting a monitor to function as both a bigger screen for my laptop, as well as my TV and gaming screen.  

I used my 23" Monitor/TV before I purchased my Bravia years back.
I had the 360, my PC, and cable hooked into it at the same time.
Since my TV is now right next to my desk I can have TV on one screen and a game/computer on another and watch both at the same time.   : )
Works out when I want to play a game but don't wanna miss a Red Sox game or something of the like.

I'm maybe go for something like this:

Monitors work great with 360's. They're usually a lot cheaper as well. It is a great option if you don't need a TV.

Well  have a used from time to time a monitor with my 360 and it sure works ..... now getting the sound output is a different thing

Thanks for the replies; looks like I'll definitely go the monitor route then!  I had a set of logitech speakers, and it looks like that one from new egg would let me plug the speakers in.  I'll shop around for a bit and see what kind of deals pop up here and there, but thanks for the feedback.  It's nice to know that it works well for you guys!

yeah, just make sure you have audio out. I have a 23" dell (has a built in web-cam & USB hub) that works great and does have audio out.

@cartvader: Nice!  Is 23" a decent size do you think?  I'm looking to spend as little as possible as I'm not HUGE into gaming, but would love to get into some MK and the occasional RPG.  Hell, I'm sure anything would look huge compared to my 13" laptop screen, haha! Although I do love the portability of it.

Asus VH236H aka the EVO monitor.

Used a 17" Sceptre monitor for my Xbox 360 back in college and worked really great, even without using an HDMI cable (used a VGA adapter).  Still looked wonderful, though.  My best friend also has a setup like yours and it definitely works for his purposes.  Monitor hooked up to both his tower and Xbox 360 with a switch to swap between inputs and a Logitech 5.1 speaker set.  Definitely a good option.

Nice, awesome to hear!  It seems like this will work out really well, thanks for the input everyone!  The switch to swap inputs sounds pretty sweet, will definitely.  Actually this morning I started slightly rethinking what I'm going to do a little bit, might just get a TV instead, not sure yet.  I was getting the Xbox 360 to run games, but a big part would have been Hulu Plus and Netflix.  I'm going to UBC in Vancouver for grad school and apparently you can't get Hulu in Canada and Netflix options blow their as well, so might have to get a TV with cable regardless :(  Blah.  
 
 So many good things about Canada, but their media and telecommunications (3 year contracts?! Pshhhh) suck big time!
