Why the hate for the Mac? By the way the trackpad has horizontal and vertical scrolling as well as both right and left click functions...
Macs have the ability to run Windows XP and Mac OS X and for several reasons I need both OSes, so a MacBook can be a pretty darn good value if you can give use to both operating systems, the X1600 is not too shabby, it comes at 300/300 which is very slow but mine works perfectly stable at 540/540 and its enough to run modern games at native res without AA or AF (Far Cry though can be completely maxed out

)
I think MacBooks are decent for the price, they are durable but the case gets banged up too easily (its cosmetical though, the internals are well protected) and they are fast not to mention OS X has a lot of apps I'm grown used to that I just can't abandon (mainly work related apps) yet I can always pop in Windows to play a game or two.
Seriously don't ditch macs just because you've never used them.
