NP.
This is my main machine now both work (Embedded design and also still work on Tier 1 Comms projects) and personal.
I generally have lots of apps/windows open when working, but most of them aren't too processor intensive (PDF's, Logs, SSH sessions, compilers, simulators, high res images, etc), although I occasionally use VMs to test cross platform compliance/compatibility.
For personal it tends to be the normal browsing/videos/light gaming to kill time/editing my amateur pics/etc. Although work generally relies on a large breadth of knowledge, so I've become conditioned to constantly flitting between some technical paper, specs of a new IC/FPGA/etc, or something else that takes my interest randomly
As you can imagine the high res display is important to me, along with decent battery life and portability because I work for myself (well my companies) so I am never really off as far as my clients are concerned (so I need a machine thats ready and with me most of the time).
No machines perfect, but this ones the best so far
