Hi Vars,
just in case you didn't realise it, this laptop is one of the new 'netbooks'. In other words, it's very small physically (great for travel), and doesn't have a cd or dvd reader/burner installed. There's just not enough room. $439 is an ok price, but I've never heard of AGL as a brand. You can get an Acer D250 for not much more, which is a bit more speccy (still doesn't have the cd/dvd tho), but at least it's a known brand.
These netbooks all use the Intel Atom N270 processor (I think), so in terms of speed, they'll all be pretty much the same I would think.
Hope his helps
