I've got an Acer Ferrari and I purchased my son an Acer Aspire, they are well built, reliable, fast machines, faultless.
However, if they do go wrong I believe the UK support is very bad as Acer do not really operate in the UK they outsource their spares and repairs to a company called Esplex in Southampton, I've read only bad things about these people, the don't honour warranties, charge the Earth and take ages to collect, repair and return, so unless you can repair the machine yourself, you'd better think carefully about our purchase.
Cheers!
