Like Léonie said, individual needs are a huge gray area each of us must personally define.
Properly set up and with SSD (Solid State Drive), the top 2011/2012 MBPs make excellent desktop replacement (DTR) boxes that will almost assuredly handle your needs (today). Needs and expectations grow with time, however, and OS/app demands also increase over time. So a new puchase is really about anticipating a variable life cycle.
Within the next week or so we will almost assuredly see multiple new Mac upgrades, including a new Mac Pro far more powerful than anything we have seen before. We should revisit this topic in 2 weeks.
Primate Labs has an excellent visual reference of the CPU performance of every past and present Mac model:

Note how much stronger Mac Pros are than the best MBPs and iMacs, even though the MPs have not had a serious upgrade in 2 years.
With the caveat that new boxes are imminent I will opine some hardware generalities regarding Aperture:
• The use of a HDD (Hard Disk Drive) for boot is a defunct concept. Everyone buying a new box should include SSD (Solid State Drive) for boot as part of the plan.
• "Desktop" does not necessarily make for a stronger setup than "laptop." Note on the benchmarks linked above that the top 2011+ MBPs are comparable to the top 2011+ iMacs. iMacs and MBPs should really be perceived as similar in power, but Mac Pros are much stronger.
• Mac Pro "towers" do make for a stronger setup than MBPs/iMacs, by a huge margin. All that beef matters:
- Power supply
- Quiet heat removal
- Upradable graphics (huge, huge issue regarding life cycle performance of a pro graphics app)
- RAM slots (cheap RAM means apps/OS designed to take advantage of much more RAM)
- Wide range of available displays; no fixed, non-upgradable, glossy display attached
- Easy drive replacements
• Graphics support has always been important to Aperture; e.g. the very strongest G5 tower would not run Aperture until the stock GPU was upgraded. Stronger (and multiple) GPUs are constantly becoming available to Mac Pros on an ongoig basis but iMacs and MBP GPUs are not upgradable, which is a significant detriment to the life cycle performance of iMacs and MBPs.
• Top iMac graphics are about 2x top MBP graphics, so top iMacs will outperform top MBPs. MP graphics are 5x the best iMac graphics, and over time the relevant graphics difference between MBP/iMac will fade but the MP relevant graphics difference can increase by upgrading.
• CPU and i/o strengths of MBP/iMac are similar. The benefits of top iMac vs. top MBP are a) extra RAM slots and b) stronger but still not upgradable GPU. The iMac detriments are a) not mobile, b) glossy display. Price is not as big a difference as one might think once SSD is included in the cost analysis.
All that said, I use a top 2011 SSD MBP and find that it drives Aperture very well. However if I did not need mobility (or if Aperture built in MBP-to-MP Library synch to the app) I would also buy a Mac Pro.
