latops are fine, from my experiences, go a Toshiba or Dell. I have a HP on it's 3rd HDD and ACER computers are just cheaply made shit no matter what you get.
If you want to game, expect to fork out over $3k for an XPS/Alienware or build a kick arse desktop.
sif bother with RAID 5 in a home application unless you plan to use Deskstar (Deathstar lol) hard disks! If you really want to get anal, buy some drives rated 24x7 or look at network attached storage.
SKITTLES: you're a macfag, 'nuff said. I work on a site with 800 pc's plus about 100 odd laptops, the shit soon floats to the surface. Even the majority of people's home computers that grace our workbench are ACER made pieces of shit.
You should also pry open your Imac some time to have a look at how it's put together (glue, tinfoil and laptop components LOLZ).
I also think you mean NETBOOKS, and yes I have a mate who works in IT in a school, they are absolutely the bane of his existence. Please tell me when you see a netbook with the performace of an i5 with the same amount of RAM, I'd love to see it
thankfully the only experience I've seen with netbooks is a limited number of Dell Latitude 2100 ones, and despite their advantages for using of asset control, network diagnostics etc, waiting 10 minutes for them to finally boot into Windows 7 was enough for me. I also think that you should look at how expensive SSD's are reletive to a netbook cost LOL.
I was also pointing out the inevitable drawbacks of gaming laptops, that the battery life is shithouse when using 2x hard disks, 2x video cards and a 17" screen, even when just surfing the net etc.
