Having never owned an Acer I can't speak for their reliability, but I would guess they would be competitive with Toshiba. Dells are not very reliable, they are CHEAP. Do not buy an HP unless you purchase their business machines. The home laptops from HP are poorly designed and break very easily.
Yes, you can buy a Vostro without owning a business
Just out of curiosity I went to check out a vostro to see if I can, but it asks for a company name. So can I just write whatever I want even if it's not a real business?
Also, I guess you're recommending toshiba then.
