The only problem with smaller notebooks is... like Teh just
said, straining. If it's for short term use, portability and
convenience, then it's should be okay lah.
Just remember your budget, if the small notebooks are going to
be expensive, and has the same price tag as a normal laptop, then
you know you're looking at the wrong one.
There is this Fujitsu one...
I wouldn't know what's best for your preferences, because to me,
as long as it works and it's durable, I'm happy.
