This is overkill unless you're going to be adding another disk at some 
point or constantly making and destroying LVs.  With a disk that small, 
it'd be totally fine to have an EFI partition of about 256M and a / 
partition taking up the rest of the space.

ext3 was in the vanilla kernel in Nov. 2001 and rapidly became 
available and really well-tested.  SuSE was heavily pushing ReiserFS, so 
I was using that for a while, but I went ext3 in 2004 or 2005.  ext2 in 
2009?

You hear "dated", I hear "has had a lot of people banging on it for a 
long time, so all the major and most of the minor bugs are fixed".  The 
main reason not to use LVM is dual booting, as nothing but Linux can 
read LVM.  With things like laptops, where you've usually only got 1 
disk, there's little benefit to LVM.

btrfs and zfs try to do too much in the same place and suffer for it.  
md has proven itself in the field, and LVM is filesystem-agnostic so if 
you want to run something other than ext4, you could.
