Web OS

It's about one and half hours ago.
I'm sitting here and waiting for my car's maintenance in Toyota's Tamsui site.
I'm sitting here and trying the google web API using their common PC in the lounge room.
It's very useful for the google's Web Desktop!
This is the first time I use the common sense of Web OS, ha!
By the way, even the lounge room here, they use the Pentium IV 3.0G for the PC.
I'm now thinking about the old old PC in my home, it's about AMD 1.4G, and the slowly performance what it does.
Is it the time for me to update my home PC right now?
