<p>Laptops were still being produced without pae support after pentium 4 came out. I have a laptop from the early 2000s (second hand, so don't know the exact year, but an old dorm mate had it as her laptop when she started uni in 2004, so I'd guess that's the year) that kernel panics on pae kernels (learned that when I put ubuntu server on in 2007). It's the edubuntu one for teaching little cousins to code now.</p>
