If you only have 7 or 8 apps on your MBP, I almost have to ask why you have it at all. I have something over 150 different applications on my iMac which, if I were to really count the ones I use even infrequently would still be something over 100. I will acknowledge that many of these are tiny, utilitarian 'applings' such as "BootChamp" which lets me quickly switch from OS X to Windows 7 without having to use any key-press 'shortcuts.'
Sorry, I just don't clutter my MBP with crap if I'm not going to use it at least a couple times per week. I have the few applications I need for work (about 4-5), MS Office, iLife, some eReader applications, some utility apps (which, btw, won't be allowed in App Store), and a handful of applications that Apple wouldn't even let sniff the App Store. Other than that, I can't even name 100 Mac applications and I certainly have no reason to rapidly change from OS X to Windows.
