I might be a little wrong and talk my own language here but..
Apps or Programs?
Are you doing stuff like photoshop? I notice you said VM's is that Virtual Machines?
That model looks to be around 1,200-1,400 USD. If all you're doing is watching movies and virtual machines, I don't think this is the place for you. If I was in your position, I'd try look for something with an intergrated graphics, nothing dedicated if you're not gaming or doing anything really graphics intensive.
The Matte Screen would be good for you, I highly recommend it if you're TRAVELING. Buzzword there. You'll get a lot of sun on your screen at times and Matte will make you fall in love for convenience.
Your G73JH doesn't seem much of an upgrade if this is all you're going to be doing. Remember these are gaming series for stuff like Crysis and Starcraft.
By all means if you do want this machine, I'd encourage you to purchase as it's simply stellar and amazing. I myself have a G750JX and I absolutely love it.. but for your purpose I cannot see a reason to fork out the extra $500 for the JW when you can find something half that price that'll meet your requirement.
I will remind you that the G750 Series is extremely bulky and difficult to find a suitable carry bag. There's only a very select few, around 4 bags I can find that're properly compatible and have sufficient padding.. in general. I still have yet to find the perfect bag.
Hope this helps, post back if there's something I've largely missed.
Personally I'd buy myself a portable DVD player that can read AVI's on a USB and take the G75 with you simply since it's a computer to use for your computing if you need it. Emails could be done on your phone, though I don't know what phone you have and if you use Outlook.
