You can default on Computer checks, and almost everything you want to do with them is stuff you can outsource easily. The major exception is Matrix Perception. With that in mind, I would actually take the Analyze CF before Computer. But Computer 1 with a spec in Analyze is not at all a waste of points.
Keep in mind that Matrix Perception is very VERY important for keeping yourself from getting hacked. I definitely recommend parking a registered Paladin sprite in your bionode with orders to spam Analyze (and keep Castling on your living persona) whenever you're on a run.
Some advice on the sprite-o-mancer:
Make sure you know what CFs and skills each sprite type you know has and can come with. You will often need to whistle up very particular types, and they have some real diversity. A cheat sheet can be really helpful here.
Spend downtime registering like crazy. It costs time but not money, and so long as you keep the rating capped at your Resonance, it almost totally risk-free (although I do suggest having a medic around; you might get KO'd by an unlucky roll from time to time). Having a bunch of registered sprites around is very important. I recommend never being without a Paladin and a Code sprite, and having a few Machine sprites with fairly generic autosoft skills (Targeting and Manuever, typically). Tutor and Crack are better Compiled for specific things.
Some of the best sprite abilities:
*Tutor sprites are ridiculously good because they can come with any Technical, Vehicle, or Knowledge skill, and they can also loan it to other people at half rating and extra time.
*Machine sprites are also ridiculously good because they can come with any Autosoft. Make sure you have a list of all the Pilot autosofts. You can in particular get it to perform any Technical or Knowledge skill.
Make sure you own a drone with arms like a Evo Orderly or Renraku Manservant for these two types to use (Tutor sprites can Command drones so they can use their skills). You may sometimes be better off having a Tutor sprite instruct another PC, and sometimes be better off having a sprite do something itself with a drone; it depends on what you have. If you have a PC with very high logic and a bunch of logic-linked skill enhancers, having a Tutor sprite instruct them can get you a bigger dice pool.
*Diagnostics is hilariously good because it works on so many things; medkits, smartguns, and in particular your hacker's commlink. Machine sprites can help people (or other sprites!) do a huge variety of tasks. Remember, though, that the assist-ee DOES need the skill because it uses teamwork.
*Probability Distrubition is also hilariously good. Again, it works well with your hacker.
*Info Sortilege is Technomagic Tea Party but hey, it never hurts. It's a free echo.
*Castling is really, really good in cybercombat. First, obviously, your Paladins sprite getting zapped is less bad than you or your hacker buddy getting zapped. Second, sprites only have Matrix Condition Monitors so they are immune to Black IC! This means if your Paladin sprite is Castling someone who is in VR, and they get hit by Blackout, the damage gets redirected to the Paladin, which is immune.
*Paladin sprites can beat pretty much anything 1v1 in cybercombat, especially high-rating ones. This is because they can get hilariously huge matrix defenses, and either punch people in the face or slowly but surely Disarm them into uselessness. A rating 6 paladin sprite with Expert Defense has 25 dice for matrix defense. A rating 10 one has 37. Most people simply can't do much of anything to that.
