Hi, These are basic questions really. But at least I can settle my mind on these forums and get some newbie help I want a 24" iMac, I have the cash but won't be going for the top model, just the next one down. So I think that's the 2.8ghz or 2.6 can't remember without looking. Anyway, does it come with a wireless adaptor built in? So basically I want to take it out the box and have it detect my wireless router straight away, will that happen!? Secondly, which is better overall, wireless keyboard and mouse or wired? My bro said the wireless arent as good, but I never asked why, however he works for a computer mag and seems to know his stuff, can anyone tell me?? Lastly, is the wireless keyboard a lot bigger? Thanks.
