Time Machine target

Gonna look for a Time Machine setup for my MacBook Pro. I don't frequently take my MacBook out so wired connection of a USB HDD is not a huge issue, though it is a bit clumsy to plug and unplug three wires every time. Moreover, my router works flawlessly in both speed and coverage, so the networking function of Time Capsule would add less to no value to my current use. Is there still a point to buy Time Capsule after all, and if so, is using Time Machine on Time Capsule reliable over wireless network?

 

Time Machine officially supports only internal HDD, directly attached ext. HDD and Time Capsule, doesn't it? I mean if I use these options, I see no difference from putting a sparse bundle on my Windows server, while both seem having quite a lot of issues per my quick skim through the net.

I am happy with it absolutely. Though a TC can enable the ac Wifi for two of my devices, it is not something really necessary (needs vs desire, ugh) as I can improve my network by enabling 5GHz (it is 802.11/n though) and repositioning my router. I foresee no stress in my wireless network either, as I won't stream like Blu-ray contents over the network... So weighting ac over a couple hundred of bucks in my case sounds a bit... wasted.

 

I know and that's why I say wired connection is not a no-go. Though I prefer those with standalone power, as still it is one wire to the Mac. Thanks anyway.
