As previously noted, the Lenovo ThinkPad X61 tablet that I use for my lectures is limping badly these days (it blue-screened this morning, whee). The options for a direct replacement are pretty limited, but in thinking about it a bit, I realized that I hardly use the tablet functions other than to annotate slides during lectures. Most of what I do with it just involves using it like an ordinary laptop.
It’s not clear to me whether the hardware is really a problem, but I might very well be able to wipe it, reinstall the necessary programs, then continue to use it as a lecture-only computer, while getting some other laptop for my fooling-people-at-coffee-shops-into-thinking-I’m-writing needs. Which means that I have a whole new query to throw out to the blog:
If I want to buy a good Windows-based laptop, what should I be looking at?
Mac and Linux cultists, please note that the Windows part of this is non-negotiable. For a variety of reasons I am constrained to Microsoft products, and I am really, really, really not interested in hearing about the wonders of the latest Apple products, or the glories of open-source, blah, blah, blah.
So, given that constraint, what product lines and features are essential for my next laptop purchase?
