would you recommend a laptop sleeve for say a 15 inch laptop, Then I can place the iPad 2 with smart cover and the Microsoft 6000 bluetooth keyboard in the sleeve?
Anyone do something like this?
I do something like that when I'm traveling. I have a Waterfield Designs "Cargo" bag that I've used for years. When I fly, I take the Cargo bag with my 15" laptop in its own sleeve in the bag and the Microsoft 6000 keyboard in a pocket in the sleeve along with the 40 lb power brick and cable separately in the bag. (Yeah, it's a slight exaggeration.) There is still sufficient room for the iPad (even in the Travel Express Case with the Origami Workstation, power cube, cable, and mobile hotspot.) And there is even room for my noise-cancelling headphones and my foldable Sennheiser portable headphones. Yeah, I know...What about the kitchen sink?
Obviously, no sane person carries all this stuff at the same time. But I need the laptop and accessories for my work. (The iPad is not a quadcore work station.) The iPad I use on the plane (in place of a netbook I used to use) and I like to have it in my hotel room for various purposes. I don't really need the additional keyboard dedicated to the iPad, but when I go to meetings with clients I can leave the big bag at the hotel and take the small Travel Express case with the Origami Workstation and Apple Wireless Keyboard.
So, to answer your question, if you need a laptop get one commodious enough to carry the iPad as well and you're all set. Obviously, unless you have a need for two keyboards, you can use the Microsoft 6000 with both your laptop and the iPad. (That assumes, of course, that you hate laptop keyboards as much as I do.)
Alternatively, just get a relatively large bag designed for a 15" laptop, (or even for a 13" laptop if you're just going to carry the iPad), possibly a sleeve for the iPad or just a cover, and a small stand to hold the iPad for typing (e.g. Belkin blade) and you're set.
