It's my personal opinion, but I'd highly recommend getting this
. It would a much better buy than that Vaio, but only if you can really afford it.
Otherwise (if you can't afford it), I suggest getting this
, it's a very good option too (and still better than that Vaio).
About Linux drivers and etc: if you're worrying about that, try looking for a Linux Distributable that has "Full Rolling Release
" type of updates (for example, Distros like "Funtoo
" (only for PROs) and "Yoper
"), they are always the most fresh (automatically updates almost every day (week, if Gentoo), or so) and basically would have almost all (if not all already) drivers that you need. But also, I should really note that it's harder for a Linux-newbie to deal with any of the ""Full Rolling Release" distros, because they aren't user-friendly (by the most part) in the beginning, and you should really read quite a few Linux FAQs and manuals, before you decide to use any of them.
And if that is your case exactly, then I highly recommend getting Ubuntu
instead, it's the most easiest Linux Distributable to use/learn from.
