2010 MBA capability

[PAC88]

I was about to get the new 11" last week but decided the screen was too small for my work on the go.. So I ordered a 2010 13" MBA with the following specs..
1.8ghz C2D cpu
4gb ram
256gb
Snow Leopard

It's not delivered yet and in the meantime I'm wondering if it's gonna be capable of performing well for me.

Right now I'm using a 2010 15" i5 MBP w/ Hi Res AG and its awesome but I need something lighter to commute with.

On average, this is what I'll be doing..

Working in Omnigraffel (main program)
-1 window open in Firefox (background)
-Music playing in iTunes while I work (background)
-Bluetooth mouse and external HD connected
-Occasionally connected to 24" 1920x1200 monitor

Will the 2010 MBA w/ the above specs do all this simultaneously without a hiccup. I already ordered it but waiting for delivery, so too late to change now. Can't wait to test it out, but right now just wondering.

Thanks

I have the same spec's except the 128 SSD.

I did not see why you can not do that and much more. Omingraffel can even be ran on the iPad.

I been one to use a mouse with a pc laptop, years past. But since I have the MBA for the last 6 months. I love the trackpad and no need for a mouse.
