Two days ago I wiped Linux off my laptop, and restored the original Windows Vista installation it came with. It's not a good way to end this machine's career, but it's being handed to someone who needs it far more than I, and I'm not going to be in a position to provide support.
I don't expect to replace marinara with another laptop anytime soon. I've found I greatly prefer the large screen and good-ol-Model-M keyboard on kalamata (the greatly-upgraded workstation) and my smartphone takes care of my general portable connectivity needs, complete with proper crypto.
About the only thing I really need a laptop for is travel involving photography, and even then it's mainly just a glorified hard drive with a screen. The Chromebook pixel looks like an ideal option (perhaps with an external hard drive) though of course I'd install a proper Linux distro on it.
In the short term, I'll use my employer-provided laptop when I need portability. Aside from the low-res screen, it's actually pretty nice system. However, I'm keeping anything personal off of it, travel excepted.
Kalamata has more than 3x the CPU oomph and 4x the RAM of marinara, plus a three-generation-newer graphics card plugged into a much larger/better (though still not all that great for photography) screen. Oh, and a real keyboard -- Even putting aside the awesomeness that is the IBM Model M, marinara's keyboard was always rather flaky.
Its main weakness is an old hard drive, which I intend to replace with something much faster (eg an SSD) soon. I'm also planning on replacing the old screen with a pair of color-accurate IPS panels, probably vertically stacked, but that will have to wait until after my finances recover from what will surely be a steep bill for the truck.
Anyway. I've migrated my 13-year-old home directories off of marinara to kalamata.. and things JustWorked. Ah, I do so love Linux!
