Hm. I might say the fact that you can't go more than 10 minutes on it but you're ok jogging around your basement is a sign that maybe jogging around the basement isn't enough anymore?
The thing is ... your body adapts to whatever exercise you give it. That's why if you're trying to lose weight and burn more calories, the advice is always to keep things mixed up. If you keep doing the same thing over and over and over again, your body learns to become more efficient at doing that thing - biologically that's how our bodies are designed - to adapt. Becoming more efficient at running is GREAT if your life depends on being able to run. It means you can run for longer, harder, faster, and expend less energy. Super if you're being hunted by sabretoothed tigers. Awful if you're trying to burn the most calories possible to lose weight.
So you need to mix things up periodically. So you've lost a good bit of weight running ... but the elliptical is a different level of intensity and a different type of movement. And right now your body is going "Whoa! New mode here! What the heck!" And I'll bet you that you burn more calories in your 10 mins on the elliptical than in 20 or 30 mins of jogging around your basement at this point. Because your body isn't adapted.
That's a good thing. You should keep going with it. Alternate jogging and elliptical. Do them both - a little of each. Keep your body guessing. I'd be willing to bet that by mixing them up a little of each, your weight loss will possibly speed up a little.
AS for the losing pounds or toning question - I'm gonna get up a little bit on a soapbox here: Toning (the type you're thinking of) is a myth. It doesn't exist. You are building cardio vascular endurance and stamina by jogging or using the elliptical. That's a good thing. It will burn calories. It doesn't "tone" anything. You can build *some* muscle using an elliptical (and by running), and espcially if you can adjust the tension or resistance on the elliptical. Doing slower but harder workouts - or doing various elevations, if you can set those, will help with some resistance to build muscle in your legs and butt. But the only way to build muscle overall is to work those muscles hard ... by lifting weights and doing body resistance work.
There. That's my exercise soapbox for the day!
But I'd say you should keep using the elliptical. It will become easier - your body will adjust. But remember, the easier it becomes, the less of a workout you're getting. So keep mixing it up so that it's not *too* easy.
