I just acquired my third laptop (using the term loosely) since getting my Brain Bag. Each has had its own Brain Cell thus far and they've never disappointed.
The new machine is a Sager NP8170-S1 and it's a behemoth. So the question is:
Will a size 1 vertical Brain Cell be large enough?
16.22" (w) x 10.87" (d) x 1.65" ~ 1.79" (h)
Fingers crossed - I really don't want to have to resort to some lesser way of keeping my computer with me. I have used my Brain Bag nearly every day since I got it about 7 years ago and I've come to rely on it.
