If anything running a Linux distro other than Android will make it less useful.
Quite the opposite. Running a fully fledged linux, with either KDE plasma netbook or unity, and having access to full desktop browsers and normal linux tools, would be a great advantage. I already have android phones and tablets, but often need to use my linux netbook for some functionality that isn't supported in android.
I really don't want a power hungry Intel CPU on a tablet, no matter how many benchmarks are faked to make it seem as fast and as low power as an equivalent Arm.
Most android apps will run without issues, that shouldn't be a problem anymore as there have been some Intel tablets out there for several months (I've seen some Asus in bargain bins at the Cora supermarket chain).
Still, the only advantage is if someone manages to run Linux on it. Might make up for the extra heat and lower battery life, to be able to run full featured Linux on it.
At its simplest, an attacker triggers a query to a domain he controls via SMTP or SSH-login. Upon receipt of the question, he can just add any answer he wants to have cached to the legit answer he provides for the query, e.g. providing two anser RR's: One for the question asked and one for a question that has never been asked — even if the DNS server is not authoritative for this domain.
He who has but four and spends five has no need for a wallet.
