Almost eight years ago I bought a cutting edge ultra-portable laptop -- the Lenovo X60s. It was, in fact, the same computer my billionaire boss was using. In Scotland, it is still my workhorse, driving an external monitor, recharging half my life via USB, etc. My $120 in upgrades from a year and a half ago is holding up quite well.
I was starting to get worried about it running hot all the time, so when I got here so I bought an external cooler, but the CPU fan is getting very rattly now, so I ordered a replacement on eBay and opened the thing up again. Turns out I had the wrong part, so I'll have to try again. It is certainly nice though to have a laptop that you can operate on without too much trouble. At this point I've been in and out of it enough that I have to remember the parts I've discarded along the way (fingerprint reader, modem wiring) or I get confused comparing mine to the how-to pictures on the internet. So far I've only lost one screw.
A big question though over the past decade or so has been "How much laptop is enough?" If you ask me, a 2006 Lenovo with an SSD and 3gigs is pretty much the sweet spot.
Unfortunately, I didn't test the Model M2 keyboard I brought with me (it is smaller than my regular M1), and it has bad capacitors. I imagine Jennifer doesn't miss my clacking keys in our flat here.
