It’s not so cut and dry for me. Travelling for me encompasses two different kinds: vacation and work.
For vacationing, the TR wins for me hands down as I don’t need a lot of power. I just need it to store my photos, check e-mail, and watch DVDs on the plane.
Work is a different story. I have been using my TR for work (i’m an independent consultant) and it has worked reasonably well. However, I often have to work at my client’s location and I do need more power and capacity than my TR provides. This is where the Type S fits in for me. The larger screen is much more comfortable for me especially for long periods of use and I can run some software much more efficiently on the S since it’s faster.
Occasionally, if I am doing short trips (like visiting the parents) I still would bring the S along especially if I have certain kinds of work to do.
At any rate, everything still hasn’t been decided yet. I’ve only had this thing for a few days so it’s not really fair for me to make any real assessment. I’m going to use it how I normally use my laptops and we’ll see how it works out.
