My auru script to show all available updates with versions and install

Question

So, I decided to hack together a little script that might be useful to someone else too.  I wanted to script that would show me all available updates, from from the official repos as well as from the aur.  I also wanted to see at a glance what the installed versions of each package and the new version to be installed are. 
The output looks something like this:
[shaun@shaun-asus-x202e ~]$ auru
Available updates from core:
vlc 2.1.2-2 2.1.2-3
Available updates from AUR:
ansible 1.4.3-1 1.4.4-1
Would you like to install all updates without further prompting?
y/n->
Here's the code that I put into a dropbox shared file called arch_functions and source it from ~/.bashrc.   Replace the test_apacman function and associated commands with aur wrapper of choice.  Once this is in place, I simply run auru once a day on all my machines and I get all the information I need, and only press a y or n in order install all updates. 
bold="\033[1m"
endbold="\033[0m"
test_apacman() {
hash apacman 2>/dev/null || \
#packer -S apacman --noedit --noconfirm
#sudo pacman -S --needed --noconfirm base-devel jshon git curl
hash wget 2>/dev/null || sudo pacman -S --needed --noconfirm wget
origdir=$(pwd)
cd ${HOME}
mkdir -p ./tmpaur/
cd ./tmpaur/
wget https://aur.archlinux.org/packages/ap/apacman/apacman.tar.gz
tar xfv apacman*
cd apacman
makepkg
sudo pacman -U --needed --noconfirm apacman-*.pkg.tar.xz
cd "$origdir"
auru() {

## check that dependencies are installed
# expac

### check core updates
pacman -Syy
echo -en "${bold}Available updates from core:${endbold}\n"
pacmanupdates=$(sudo pacman -Qu)
for pacmanupdate in "$pacmanupdates"
do

then
echo "No core updates"

#echo -en "$pkg\t$pkgvernow\t$pkgveravail\n"
printf '%-25s' "$pkg"
printf '%-20s' "$pkgvernow"
printf '%-20s\n' "$pkgveravail"
updatesavail=$((updatesavail + 1))
fi
done
### check aur updates
echo -en "${bold}Available updates from AUR:${endbold}\n"
aurupdates=$(apacman --auronly --quickcheck)
for aurupdate in "$aurupdates"
do
if [ "$aurupdate" == "" ]
then
echo "No AUR updates"
else
pkg="$aurupdate"
pkgvernow=$(sudo pacman -Q ${pkg} | awk '{print $2}')
pkgveravail=$(apacman -Ss ${pkg} | grep "aur/${pkg} " | awk '{print $2}')
printf '%-25s' "$pkg"
printf '%-20s' "$pkgvernow"
printf '%-20s\n' "$pkgveravail"
updatesavail=$((updatesavail + 1))
fi
done
### apply updates if any
if [ $updatesavail -gt 0 ]
then
echo "Would you like to install all updates without further prompting?"
read -p "y/n->" answer
if [ "$answer" == "y" ]
then
sudo pacman -Su --noconfirm
apacman -Su --auronly --noedit --noconfirm --needed
fi
fi

For someone with a username like yours I would have expected better. I guess you are not a "tech guy" at all. After a while Apple improves the hardware, and updates iOS to take advantage of the features and speed of the newer hardware. Older devices are simply incapable of taking advantage of the newer features, because the hardware doesn't support it. There's a lot of advice posted in the forum from people who warn that you shouldn't upgrade an iPhone 4S to iOS 8, because it kills the performance. If that's true, imagine how iOS 8 must perform on an iPhone 4. 
By your reasoning I should be able to run Windows 10 on a 1985 IBM PC. The only reason you can't is because Microsoft had a deal with hardware manufacturers to force people to get new computers.
Or are you arguing that Apple should never improve hardware, because it will leave users of older phones in the lurch?
